In the title compound, [Zn4(C16H10N4O2)4]·4H2O, the N′-[(8-oxidoquinolin-7-yl)methylidene]isonicotinohydrazidate (L 2−) ligand binds to the metal ions, forming stable five- and six-membered chelate rings, leaving the pyridyl groups free. The compound is a tetranuclear ZnII complex centered about a fourfold roto-inversion axis, with the ligand coordinating in the doubly deprotonated form. The ZnII atom has a distorted square-pyramidal geometry being coordinated by one N and two O-atom donors from the doubly deprotonated L 2− ligand, and by one N atom and one O-atom donor from a symmetry-related L 2− ligand. In the crystal, four symmetry-related lattice water molecules, centred about a fourfold roto-inversion axis, form a cyclic tetramer through O—H...O hydrogen bonds. These tetramers connect to the complex molecules through O—H...N hydrogen bonds, forming a chain propagating along [100]. Neighbouring molecules are linked by π–π interactions [centroid–centroid distance = 3.660 (2) Å] involving the quinolidine rings.

In the title compound, [Cu2(C7HF4O2)4(C12H8N2)2]·2H2O, the CuIIion has a square-pyramidal coordination sphere. The basal plane consists of two N atoms [Cu—N = 2.008 (3) and 2.032 (3) Å] from the phenanthroline ligand, and of two carboxylate O atoms [Cu—O = 1.942 (3) and 1.948 (3) Å] from two 2,3,4,5-tetrafluorobenzoate anions. Another 2,3,4,5-tetrafluorobenzoate anion provides the apical carboxylate O atom [Cu—O = 2.262 (3) Å] and bridges two CuIIions into a binuclear centrosymmetric dimer. Intramolecular π–π interactions between one of the tetrafluorobenzene rings and the middle of the phenenanthroline rings [3.617 (3) Å] stabilize the molecular configuration. O—H...O hydrogen bonds between the lattice water molecules and the unbound carboxylate O atoms of the metal complexes leads to the formation of a chain structure parallel to [100].

In the crystal, a network of O—H...O hydrogen bonds involving the P(O)(O−)(OEt) groups, bridging hydroxyl groups, coordinated and uncoordinated water molecules generates a three-dimensional supramolecular structure. The ethyl group exhibits disorder and was modelled over three sites with occupancies of 0.455, 0.384 and 0.161.

In the title compound, [Cu2Cl4(C12H8N2O4)2]·4C3H7NO, which contains a chloride-bridged centrosymmetric CuIIdimer, the CuIIatom is in a distorted square-pyramidal 4 + 1 coordination geometry defined by the N atoms of the chelating 2,2′-bipyridine ligand, a terminal chloride and two bridging chloride ligands. Of the two independent dimethylformamide molecules, one is hydrogen bonded to a single –COOH group, while one links two adjacent –COOH groupsviaa strong accepted O—H...O and a weak donated C(O)—H...O hydrogen bond. Two of these last molecules and the two –COOH groups form a centrosymmetric hydrogen-bonded ring in which the CH=O and the –COOH groups by disorder adopt two alternate orientations in a 0.44:0.56 ratio. These hydrogen bonds link the CuIIcomplex molecules and the dimethylformamide solvent molecules into infinite chains along [-111]. Slipped π–π stacking interactions between two centrosymmetric pyridine rings (centroid–centroid distance = 3.63 Å) contribute to the coherence of the structure along [0-11].
