The CdII atom in the title complex, [Cd(C8H5O3)2(C12H8N2)(H2O)], is coordinated by three O atoms of two formylbenzoate ligands, two N atoms of a 1,10-phenanthroline ligand and one water molecule, giving rise to a trigonal–prismatic coordination geometry. Adjacent complex molecules are linked into a two-dimensional layer structure via hydrogen-bonding interactions.

The title compound, {[Ag(C6H7AsNO3)(C18H15P)]·H2O}n, has been synthesized from the reaction of 4-aminophenylarsonic acid with silver nitrate, in aqueous ammonia, with the addition of triphenylphosphane (PPh3). The AgIcentre is four-coordinated by one amino N atom, one PPh3P atom and two arsonate O atoms, forming a severely distorted [AgNPO2] tetrahedron. Two AgI-centred tetrahedra are held together to produce a dinuclear [Ag2O2N2P2] unit by sharing an O–O edge. 4-Aminophenylarsonate (Hapa−) adopts a μ3-κ3N:O:O-tridentate coordination mode connecting two dinuclear units, resulting in a neutral [Ag(Hapa)(PPh3)]nlayer lying parallel to the (10\overline{1}) plane. The PPh3ligands are suspended on both sides of the [Ag(Hapa)(PPh3)]nlayer, displaying up and down orientations. There is anR22(8) hydrogen-bonded dimer involving two arsonate groups from two Hapa−ligands related by a centre of inversion. Additionally, there are hydrogen-bonding interactions involving the solvent water molecules and the arsonate and amine groups of the Hapa−ligands, and weak π–π stacking interactions within the [Ag(Hapa)(PPh3)]nlayer. These two-dimensional layers are further assembled by weak van der Waals interactions to form the final architecture.

The mononuclear title complex, [Fe(CF3O3S)(C5H7O2)2(C4H8O)] or [Fe(acac)2(OTf)(THF)] (acac = acetylacetonate; OTf = trifluoromethanesulfonate; THF = tetrahydrofuran), (I), consists of one six-coordinate Fe3+atom in a slightly distorted octahedral environment [Fe—O bond-length range = 1.9517 (11)–2.0781 (11) Å]. The triflate ligand was found to be disordered over two sets of sites, with a site-occupancy ratio of 0.622 (16):0.378 (16). Weak intermolecular C—H...O and C—H...F hydrogen-bonding interactions generate a two-dimensional supramolecular structure lying parallel to (100). This is only the second crystal structure reported of a mononuclear bis(acetylacetonato)iron(III) complex.

The title mononuclear CuIIcomplex, [Cu(C8H5O3)2(C10H8N2)], is comprised of a CuIIcation, two 4-formylbenzoate (L−) ligands and a 2,2′-bipyridine (bipy) ligand. The CuIIion and bipy ligand lie on a crystallographic twofold rotation axis; the CuIIion is coordinated by two N atoms from one bipy ligand and two O atoms from two different carboxylate groups of twoL−ligands, exhibiting effectively a distorted square-planar geometry. The complex molecules are interlinked to generate two-dimensional supramolecular layers in theabplane, formed by C—H...O hydrogen bonds, where the O acceptor is the O atom from the carboxylate group not involved in coordination to the CuIIion. The two-dimensional layers are stacked in a sequenceviaC—H...O hydrogen-bonding interactions where the formyl O atom acts as acceptor.

The structure of the title caesium salt with salicylic acid, poly[μ2-aqua-μ4-(salicylato-κ4O1:O1:O1′:O2)caesium], [Cs(C7H5O3)(H2O)]n, represents a second monoclinic polymorph of this compound. The two-dimensional coordination polymeric structure is based on a centrosymmetric dinuclear bridged repeat unit with each irregular CsO6coordination polyhedron comprising a μ2-bridging water molecule and μ4-bridging O-atom donors, three from the carboxyl group and one from the phenolic group of the salicylate ligand. The Cs—O bond range is 3.023 (3)–3.368 (4) Å and the Cs...Cs separation within the dinuclear unit is 4.9265 (6) Å. The polymeric sheet structure lies parallel to (010) with the water molecule and the phenol group involved in intra-polymer O—H...Ocarboxylhydrogen-bonding interactions.

The asymmetric unit of the title compound, [Ag3Yb(C5HN2O4)2(H2O)2]n, contains three AgIions, one YbIIIion, two imidazole-4,5-dicarboxylate ligands and two coordinating water molecules. The YbIIIatom is eight-coordinated, in a bicapped trigonal prismatic coordination geometry, by six O atoms from three imidazole-4,5-dicarboxylate ligands and two coordinating water molecules. The two-coordinated AgIions exhibit three types of coordination environments. One AgIatom is bonded to two N atoms from two different imidazole-4,5-dicarboxylate ligands. The other two AgIatoms are each coordinated by one O atom and one N atom from two different imidazole-4,5-dicarboxylate ligands. These metal coordination units are connected by bridging imidazole-4,5-dicarboxylate ligands, generating a two-dimensional heterometallic layer. These layers are stacked along theaaxisviaO—H...O hydrogen-bonding interactions to generate a three-dimensional framework.
