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 asymmetric unit of the title compound, C6H5Cl2NO2S, contains two molecules with similar conformations (r.m.s. overlay fit for the non-H atoms = 0.067 Å). Atoms attached to the pendent Csp3—S bond are arranged in a staggered conformation with one of the Cl atomsantito the C atom in the aromatic ring [C—S—C—Cl torsion angles = 178.41 (11) and −176.70 (13)°]. In the crystal, molecules are linked by C—H...N and C—H...O hydrogen bonds, generating a three-dimensional network, and weak aromatic π–π stacking is also observed [centroid–centroid separation = 3.8902 (17) 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 title compound, [Cu4Cl8(C6H14N4O2)4], contains four molecules in the asymmetric unit. In the molecular structure, each of the four Cu2+ions binds to three Cl atoms, one N atom and one O atom, resulting in distorted square-pyramidal coordination environments. The molecular structure is stabilized by weak C—H...O and N—H...Cl hydrogen bonds. The crystal structure exhibit weak intermolecular N—H...O, C—H...O and N—H...Cl interactions, generating a three-dimensional network.

In the crystal structure of the title compound, (C3H11NOP)2[PdCl4], (dimethylphosphoryl)methanaminium (dpmaH+) cations are connected head-to-tail by strong N—H...O hydrogen bonds, forming inversion-related cyclic dimers. The square-planar [PdCl4]2−counter-dianion is located about a center of inversion. The dications and the [PdCl4]2−dianions are connected by medium–strong N—H...Cl hydrogen bonds, forming zigzag chains parallel to [001]. Somewhat weaker N—H...Cl hydrogen bonds connect the chains into a three-dimensional network.

The molecular shape of the title compound, C16H12O7, is bent around the central CH2—O bond. The two benzene rings are almost perpendicular to one another, making a dihedral angle of 87.78 (7)°. In the crystal, each molecule is linked to three others by three pairs of O—H...O hydrogen bonds, forming undulating sheets parallel to thebcplane and enclosingR22(8) ring motifs. The sheets are linked by C—H...O hydrogen bonds and C—H...π interactions, forming a three-dimensional network.

In an attempt to brominate 1,4-dipropoxy-9,10-anthraquinone, a mixture of products, including the title compound, C14H7BrO4, was obtained. The molecule is essentially planar (r.m.s. deviation = 0.029 Å) and two intramolecular O—H...O hydrogen bonds occur. In the crystal, the molecules are linked by weak C—H...O hydrogen bonds, Br...O contacts [3.240 (5) Å], and π–π stacking interactions [shortest centroid–centroid separation = 3.562 (4) Å], generating a three-dimensional network.

The title compound, C6H12O6, was crystallized from an aqueous solution of equimolar mixture of D- and L-fructose (1,3,4,5,6-pentahydroxyhexan-2-one,arabino-hexulose or levulose), and it was confirmed that D-fructose (or L-fructose) formed β-pyranose with a2C5(or5C2) conformation. In the crystal, two O—H...O hydrogen bonds between the hydroxy groups at the C-1 and C-3 positions, and at the C-4 and C-5 positions connect homochiral molecules into a column along theaaxis. The columns are linked by other O—H...O hydrogen bonds between D- and L-fructose molecules, forming a three-dimensional network.

The title compound, [Au(C18H10F4PS)Cl2], crystallizes as neutral molecules, with the AuIIIatom coordinated by two Cl atoms and by the P and S atoms of the bidentate phosphanyl thiolate ligand, in a slightly distorted square-planar environment. The molecules are linked into centrosymmetric dimersvialong axial Au—Cl bonds of 3.393 (4) Å. This axial Au—Cl distance is longer than is usually seen, although one other example has been given. Dimer formation may explain the unexpectedly low solubility of the compound in common polar solvents. There is also a separate intermolecular Au—F contact of 3.561 (6) Å, but this distance seems too long to be regarded as a bond. Two putative C—H...F hydrogen bonds appear to link the dimers into sheets parallel to (110). There is a short intermolecular F...F contact of 2.695 (10) Å between two dimers related by the twofold axis.

In the tetraborate anion of the title compound, K2[B4O5(OH)4]·H2O, the bridging B—O bond lengths of the tetrahedral BO4 and the trigonal-planar BO3 units are slightly longer than the corresponding terminal B—OH bond lengths. The crystal structure is stabilized by intermolecular O—H...O, O—H...Owater and Owater—H...O hydrogen bonds, generating a three-dimensional network. The two potassium cations both show a coordination number of 9.

In the title compound, C19H20ClN3O4S, the benzene ring is inclined to the indazole ring system (r.m.s. deviation = 0.014 Å) by 65.07 (8)°. The allyl and ethoxy groups are almost normal to the indazole ring, as indicated by the respective torsion angles [N—N—C—C = 111.6 (2) and C—C—O—C = −88.1 (2)°]. In the crystal, molecules are connected by N—H...N hydrogen bonds, forming helical chains propagating along [010]. The chains are linked by C—H...O hydrogen bonds, forming a three-dimensional network.
