The title compound, [Pd(C11H6O3)(C10H8N2)]·0.5H2O, contains two monoclear PdII complexes and one water molecule in the asymmetric unit. The Pd atom of each complex has a similar distorted cis-square-planar coordination geometry and is bonded to two N atoms from 2,2′-bipyridine ligand, and one carboxylate O and one naphthol O atom from the 3-oxidonaphthalene-2-carboxylate ligand. There are intermolecular π–π interactions, together with hydrogen bonds involving the solvent water molecule.

The title complex, [Ag2(C7H5O3)2(H2O)2]·4H2O, is a centrosymmetric bis(carboxylato-κ2O,O′)-bridged binuclear dimer with a strong Ag—Ag interaction. Each AgI atom has a four-coordinate square-planar geometry, in which it is bonded to two carboxylate O atoms, one water O atom and the other AgI atom. All the coordinated and uncoordinated water molecules are disordered; they form a cluster around the dimer through intermolecular hydrogen-bond networks, linking the complex molecules to each other.

In the crystal structure of the title binuclear iron(III) complex, [FeO(SO4)2(C12H8N2)4]·8H2O, the Fe atoms are connected by an O atom, which lies on a twofold axis. Each Fe atom is also coordinated by four N atoms of two 1,10-phenanthroline ligands and one O atom of a sulfate ion, resulting in a distorted octahedral geometry. The FeFe separation is 3.5552 (21) Å and the Fe—O—Fe bridge angle is 172.81 (12)°. The crystal packing is stabilized by a network of O—HO hydrogen bonds.

In the title complex, [Pd(C6H4O2)(C10H8N2)], the central Pd atom has a distorted cis planar four-coordination geometry defined by two O atoms of the benzene-1,2-diolate dianion and the two N atoms of a 2,2′-bipyridine ligand. The molecule is essentially planar.

In the crystal structure of the title complex, [Zn(C10H6NO2)2(CH3OH)2], the Zn atom at a center of inversion has distorted octahedral coordination geometry and is bonded to two quinoline N atoms, two carboxylate O atoms and two methanol O atoms. Two isoquinoline-3-carboxylate ligands lie in trans positions, forming the equatorial plane, and the two methanol ligands occupy the axial positions. The complex molecules are linked together by O—HO hydrogen bonds between the methanol ligands and neighboring carboxylate groups.

The redetermined structure of the title compound, [Cu(C2H4NO2)Cl(C10H8N2)]·2H2O, confirms that reported earlier [Neitzel & Desiderato (1975). Cryst. Struct. Commun. 4, 333–336] with respect to the non-H atoms. All the H atoms have been located in the present study and the network of N—HO, N—HCl, O—HO and O—HCl hydrogen bonds has been elucidated.

In the structure of the title complex, 2[PtCl2(C18H12N2)]·C18H12N2, the metal complex and a free 2,2′-biquinoline molecule are present in a 2:1 ratio. The cocrystallized molecule of 2,2′-biquinoline lies about a center of symmetry. The four-coordinate Pt atom has a distorted cis-square-planar geometry and is bonded by the two N atoms of a 2,2′-biquinoline ligand and two anionic Cl− ions. The overall structure of the metal complex is not planar, and the Pt and Cl atoms deviate significantly from the plane of the 2,2′-biquinoline ligand.

In the title compound, {[(2-aminoethyl)iminomethyl]phenolato-κ3N,N′,O}(9H-purine-6-aminato-κN9)palladium(II) 3.5-hydrate, [Pd(C5H4N5)(C9H11N2O)]·3.5H2O, the PdII ion is coordinated by the N9 atom of the adeninate ligand, two N atoms and one O atom of the N-(2-aminoethyl)salicylideneiminate in a square-planar coordination. The crystal structure is stabilized by centrosymmetric stacking interactions between neighbouring complexes, and by hydrogen bonds involving adeninate and N-(2-aminoethyl)salicylideneiminate ligands, and non-coordinated water molecules.
