(Acetato-κO)bis­(1,10-phenanthroline-κ2N,N′)copper(II) acetate hepta­hydrate

In the title complex, [Cu(CH3CO2)(C12H8N2)2](CH3CO2)·7H2O, the central CuII ion is five coordinate, being bound to four N atoms from two 1,10-phenanthroline ligands and one O atom from an acetate anion in a strongly distorted square-pyramidal configuration. Hydrogen-bonded water molecules and an uncoordinated acetate anion form a two-dimensional polymeric structure parallel to (010). The cations are linked to this layer via O—H⋯O hydrogen bonds between one of the water molecules and the coordinated acetate anion.

In the title complex, [Cu(C17H15NO5)(C12H8N2)]·2H2O, the central CuII ion is five-coordinate, bound to one N atom and two O atoms from the Schiff base ligand and by two N atoms from a 1,10-phenanthroline ligand in a distorted square-pyramidal configuration. In the crystal, intermolecular O—H⋯O and C—H⋯O hydrogen bonds form a two-dimensional network parallel to (001).

Oxido[N-(2-oxidobenzyl-idene-κO)leucinato-κ²N,O](1,10-phenanthroline-κ²N,N')vanadium(IV).

In the title VIV complex, [VO(C13H15NO3)(C12H8N2)], the oxidovanadium cation is N,N′-chelated by a 1-10-phenanthroline ligand and N,O,O′-chelated by a Schiff base anion in a distorted octahedral geometry. Weak intermolecular C—H⋯O hydrogen bonds occur in the crystal structure which contains solvent-accessible voids of 81 Å3.

[N-(3-Meth­oxy-2-oxidobenzyl­idene-κO 2)leucinato-κ2 N,O](1,10-phenanthroline-κ2 N,N′)copper(II) monohydrate

The asymmetric unit of the title complex, [Cu(C14H17NO4)(C12H8N2)]·H2O, contains two independent CuII complex molecules and two uncoordinated water molecules. In each complex molecule, the Cu atom is O,N,O′-chelated by the tridentate Schiff base ligand and N,N′-chelated by the 1,10-phenanthroline ligand in a distorted square-pyramidal geometry. The Cu—N bond distances in the apical directions are 2.298 (4) and 2.268 (4) Å. In the crystal, intermolecular O—H⋯O and C—H⋯O hydrogen bonds together with C—H⋯π interactions result in a three-dimensional supramolecular structure.
