In the monomeric title complex, [Cd(C2O4)(CH3N5)2(H2O)2], the CdIIion exhibits a distorted octahedral coordination geometry, with the equatorial plane defined by two O atoms from an oxalate ligand and two N atoms from two 5-amino-1H-tetrazole ligands; the axial sites are occupied by two water molecules, with longer Cd—O bond lengths. An intramolecular N—H...O hydrogen bond occurs. In the crystal, N—H...O as well as O—H...O and O—H...N hydrogen bonds (some of which are bifurcated) link the complex molecules into a three-dimensional network.

In the title compound, [Zn(C8H5N5O3)(C12H8N2)(H2O)]·3H2O, a tridentate 2-amino-7-methyl-4-oxidopteridine-6-carboxylate ligand, a bidentate ancillary 1,10-phenanthroline (phen) ligand and a water molecule complete a distorted octahedral coordination geometry around the ZnIIatom. The pterin ligand forms two chelate rings. The phen and pterin ring systems are nearly perpendicular [dihedral angle = 85.16 (5)°]. Classical N—H...O, O—H...N and O—H...O hydrogen bonds and weak C—H...O hydrogen bonds link the complex molecules and lattice water molecules into a three-dimensional network. π–π stacking contacts are observed as well, with centroid-to-centroid distances of 3.5679 (14), 3.7004 (14), 3.6641 (15), 3.6974 (13) and 3.3412 (12) Å.

The Ni atom in the title complex, [Ni(C2H3O2)2(C15H13N5)] or [Ni(CH3COO)2(tpdaH2)] (tpdaH2 is tripyridyldiamine), has a distorted octahedral coordination geometry formed by the tridentate tpdaH2 ligand and two acetate groups. The tpdaH2 ligand is mer-coordinated, with the N atom of the central pyridine ring in the equatorial position and the N atoms of the peripheral pyridine rings in the axial positions. The remaining three equatorial positions are occupied by the O atoms of two acetate anions. The H atoms of both NH groups of the tpdaH2 ligand are involved in strong hydrogen bonds with O atoms of adjacent complex molecules to form a three-dimensional network.

The dinuclear title complex, [Co2(C15H8O7)2(H2O)6], lies across an inversion center. The unique CoIIion is coordinated in a slightly distorted octahedral coordination geometry by two O atoms from a chelating 4-(carboxyphenoxy)phthalate ligand, three water O atoms and a further O atom from a bridging carboxylate group of a symmetry-related 4-(carboxyphenoxy)phthalate ligand. In the crystal, O—H...O hydrogen bonds link the molecules into a three-dimensional network.

The CoIIion in the title complex, [Co(SO4)(C13H8N4)(H2O)2]n, has a slightly distorted octahedral coordination environment formed by two O atoms from two symmetry-related bridging sulfate ligands, two N atoms from a bis-chelating 1H-imidazo[4,5-f][1,10]phenanthroline (IPL) ligand and two O atoms from coordinated water molecules. The bridging sulfate ligands connect CoIIions to form a one-dimensional chain along theb-axis direction. In the crystal structure, intermolecular O—H...O, O—H...N and N—H...O hydrogen bonds link the chains into a three-dimensional network.

In the title complex, [Ru(C12H8N2)2(C5H6N2)2](PF6)2, the RuIIatom is bonded to two α-diimine ligands,viz.1,10-phenanthroline (phen), in acisconfiguration, in addition with with two 4-aminopyridine (4Apy) ligands, resulting in a distorted octahedral coordination geometry. N—H...F hydrogen-bonding interactions play an important role in the crystal assembly: 21-screw-axis-related complex molecules and PF6−counter-ions alternate in helical chains formed along theaaxis by means of these contacts. N—H...π contacts (H...centroid = 3.45 Å) are responsible for cross-linking between the helical chains along [001].
