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

In the title complex, [Cu(C12H13NO5)(C12H8N2)]·0.5H2O, the CuII ion is five-coordinated by one N atom and two O atoms from a tridentate Schiff base ligand, derived from the condensation of l-threonine and o-vanillin, and two N atoms from a 1,10-phenanthroline ligand in a distorted square-pyramidal geometry. In the crystal, inter­molecular O—H⋯O hydrogen bonds form a one-dimensional left-handed helical structureextending parallel to [001]. The water molecule of crystallization shows half-occupancy

{2-(4-Hy­droxy­phen­yl)-2-[(3-meth­oxy-2-oxidobenzyl­idene)amino-κ2 O 2,N]propanoato-κO}(1,10-phenanthroline-κ2 N,N′)copper(II) dihydrate

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)

[N-(3-Methoxy-2-oxidobenzylidene-κO2)leucinato-κ2N,O](1,10-phenanthroline-κ2N,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

(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
