The title compound, cis-[PtCl2(CH3NH2)2], was obtained from the reaction of K2PtCl4 with CH3NH2·HCl and CH3COOK. The single-crystal structure has been reported previously [Wimmer, Wimmer, Jaud, Johnson & Castan (1988). Inorg. Chim. Acta, 144, 25–30], but no three-dimensional coordinates are available. We have carried out an ab initio crystal structure determination using X-ray powder diffraction techniques. The crystal structure consists of discrete molecules, with the PtII atom in a slightly distorted square-planar coordination environment. The methyl groups lie on the same side of the plane defined by the two N and two Cl atoms. Molecules are connected via intermolecular N—H...Cl hydrogen bonds to form two-dimensional layers perpendicular to the b axis. The methylamine groups protrude from these layers, forming organic interlayers.

In the title polymeric complex, {[FePt(CN)4(H2O)2]·2C3H6O} n , the FeII cation has an octahedral [FeN4O2] geometry being coordinated by two water molecules and four cyanide anions. The Pt cation is located on an inversion centre and has a square-planar coordination environment formed by four cyanide groups. The tetracyanoplatinate anions bridge the FeII cations to form infinite two-dimensional layers that propagate in the bc plane. Two guest molecules of acetone per FeII are located between the layers. These guest acetone molecules interact with the coordinated water molecules by O—H...O hydrogen bonds.

The dinuclear title compound, [PdCl{Se[(C5H5)Fe(C5H3)2CH2N(CH3)2]}]2was obtained by the reaction of [PdCl2(NCPh)2] with 2-[(N,N′-dimethylamino)methyl]ferroceneselenolate and the crystals for the structure determination were grown from a mixture of THF andn-hexane. Both PdIIatoms are coordinated by the bridging Se atoms and by the amino N atoms of the bidentate 2-[(N,N′-dimethylamino)methyl]ferroceneselenolate ligand, as well as by Cl atoms, and show a distorted square-planar coordination. The angle between the Pd—Se—Se planes of the two Pd atoms is 149.31 (3)°. Weak Cl...H hydrogen bonds link the binuclear complexes into a three-dimensional network.

The crystal structure of KIO3•HIO3 has been determined by three-dimensional single crystal X-ray diffraction and by neutron powder diffraction. The crystallographic data are a = 7.025(2), b = 8.206(2), c = 21.839(5) Å, β = 97.98(2)°, space group P21/c, Z = 8 units KIO3•HIO3. The residual [Formula: see text] was 0.048 for 7516 independent X-ray reflections measured on a three-circle diffractometer with Zr-filtered Mo radiation. The results of the present study show good qualitative agreement with the structure recently determined by Chan and Einstein (7). The HIO3 and [Formula: see text] groups are pyramidal, the I—O(H) bonds vary from 1.898 to 1.939(4) Å and the I—O bonds from 1.786 to 1.827(4) Å, these lengths are not corrected for the effects of thermal motion. Strong O—I … O interactions and electrostatic attractions between K+ and Oδ− give slabs of thickness [Formula: see text] The slabs are connected by hydrogen bonds of 2.710 and 2.694 Å.

The title compound, [NiBr(C25H29N2O)], contains an NiII atom with a slightly distorted square-planar coordination environment defined by one O and two N atoms from the 2-{[(8-aminonaphthalen-1-yl)imino]methyl}-4,6-di-tert-butylphenolate ligand and a bromide anion. The Ni—O and Ni—N bond lengths are slightly longer than those observed in the phenyl backbone counterpart, which can be attributed to the larger steric hindrance of the naphthyl group in the structure of the title compound. The molecule as a whole is substantially distorted, with both the planar naphthalene-1,8-diamine and imino–methyl–phenolate substitutents rotated against the NiN2OBr plane by 38.92 (7) and 37.22 (8)°, respectively, giving the molecule a twisted appearance. N—H...Br hydrogen bonds and N—H...C(π) contacts connect the molecules into dimers, and additional C—H...Br contacts, C—H...π interactions, and an offset stacking interaction between naphthyl units interconnect these dimers into a three-dimensional network.

The asymmetric unit of the title compound, [Ni(NCS)2(C12H9NO)2(CH3OH)2]·CH3OH, comprises one NiII cation, two thiocyanate anions, two 4-benzoylpyridine coligands, two coordinating, as well as one non-coordinating methanol molecule. The NiII cation is coordinated by two terminally N-bonded thiocyanate anions, the N atoms of two 4-benzoylpyridine coligands and the O atoms of two methanol ligands within a slightly distorted octahedron. Individual complexes are linked by intermolecular O—H...S hydrogen bonding into chains parallel to [010] that are further connected into layers parallel to (10\overline{1}) by C—H...S hydrogen bonds. Additional C—H...O hydrogen-bonding interactions lead to the formation of a three-dimensional network that limits channels extending parallel to [010] in which the non-coordinating methanol molecules are located. They are hydrogen-bonded to the coordinating methanol molecules. X-ray powder diffraction revealed that the compound could not be prepared as a pure phase.

The one-dimensional coordination polymercatena-poly[diaqua(sulfato-κO)copper(II)]-μ2-glycine-κ2O:O′], [Cu(SO4)(C2H5NO2)(H2O)2]n, (I), was synthesized by slow evaporation under vacuum of a saturated aqueous equimolar mixture of copper(II) sulfate and glycine. On heating the same blue crystal of this complex to 435 K in an oven, its aspect changed to a very pale blue and crystal structure analysis indicated that it had transformed into the two-dimensional coordination polymer poly[(μ2-glycine-κ2O:O′)(μ4-sulfato-κ4O:O′:O′′:O′′)copper(II)], [Cu(SO4)(C2H5NO2)]n, (II). In (I), the CuIIcation has a pentacoordinate square-pyramidal coordination environment. It is coordinated by two water molecules and two O atoms of bridging glycine carboxylate groups in the basal plane, and by a sulfate O atom in the apical position. In complex (II), the CuIIcation has an octahedral coordination environment. It is coordinated by four sulfate O atoms, one of which bridges two CuIIcations, and two O atoms of bridging glycine carboxylate groups. In the crystal structure of (I), the one-dimensional polymers, extending along [001], are linkedviaN—H...O, O—H...O and bifurcated N—H...O,O hydrogen bonds, forming a three-dimensional framework. In the crystal structure of (II), the two-dimensional networks are linkedviabifurcated N—H...O,O hydrogen bonds involving the sulfate O atoms, forming a three-dimensional framework. In the crystal structures of both compounds, there are C—H...O hydrogen bonds present, which reinforce the three-dimensional frameworks.

A Chain

In the title compound, [Co(C8H5O4)(C9H6N7)]n, the divalent CoIIatom is six-coordinated to three N atoms from two symmetrical 5-(pyridin-4-yl)-1H,2′H-3,3′-bi[1,2,4-triazole] (H2pyttz) ligands and three O atoms from three symmetrical 3-carboxybenzoate (Hbdic) ligands, leading to a distorted {CoN3O3} octahedral coordination environment. Two CoIIcations are linked by four bridging carboxylate groups to generate a dinuclear [Co2(CO2)4] unit. The dinuclear units are further connected into a chain along [010]viathe Hbdic ligands. The other infinite chain, along [100], is formed through the H2pyttz ligands. Finally, the two kinds of chains are cross-linked, by sharing the CoIIcations, into a two-dimensional network. In the crystal, adjacent layers are further linked by O—H...N hydrogen bonds into a three-dimensional framework.

A novel metal–organic framework, {[Zn2Cl4(C25H24N4O4)]·4C3H7NO}n, has been synthesized solvothermally by assembling the semi-rigid tetrahedral ligand tetrakis[(pyridin-4-yl)oxymethyl]methane (tpom) and zinc nitrate in dimethylformamide (DMF). The crystal structure is noncentrosymmetric (P\overline{4}21c). Each ZnIIcation has a tetrahedral coordination environment (C2symmetry), which is formed by two chloride ligands and two pyridine N atoms from two tpom ligands. The tetrahedral tetradentate tpom linker has a quaternary C atom located on the crystallographic \overline{4} axis. This linker utilizes all the peripheral pyridine N atoms to connect four ZnIIcations, thereby forming a wave-like two-dimensional sheet along thecaxis. The two-dimensional layer can be topologically simplified as a typical uninodal 4-connected sql/Shubnikov net, which is represented by the Schläfli symbol {44,62}. Adjacent layers are further packed into a three-dimensional structure by C—H...Cl hydrogen bonds.

A nickel(II) terephthalate complex, viz. [Ni(C6H4N2)2(H2O)4](O2CC6H4CO2)·4H2O, has been synthesized and studied by single-crystal X-ray diffraction. It crystallizes in the triclinic space group P\overline{1}. The crystal structure shows an approximately octahedral coordination environment of the complex with the [Ni(H2O)4(3-NCpy)2]2+ (3-NCpy is pyridine-3-carbonitrile) cation associated with four free water molecules and hydrogen bonded to a terephthalate dianion [graph set R 2 2(8)]. The supramolecular structure of the compound is stabilized by a three-dimensional array of O—H...O and O—H...N hydrogen bonds, along with π–π stacked pyridine-3-carbonitrile rings and C—H...O interactions.

The asymmetric unit of the title compound, [Ni(C52H34Cl4N4O4)]·CH2Cl2, consists of two discrete complexes, which show significant differences in the conformation of the side chain. Each NiII cation is coordinated by four nitrogen atoms of a porphyrin molecule within a square-planar coordination environment. Weak intramolecular C—H...Cl and C—H...O interactions stabilize the molecular conformation. In the crystal structure, discrete complexes are linked by C—H...Cl hydrogen-bonding interactions. In addition, the two unique dichloromethane solvate molecules (one being disordered) are hydrogen-bonded to the Cl atoms of the chlorophenyl groups of the porphyrin molecules, thus stabilizing the three-dimensional arrangement. The crystal exhibits pseudo-orthorhombic metrics, but structure refinements clearly show that the crystal system is monoclinic and that the crystal is twinned by pseudo-merohedry.
