(Benzoato-κO)(benzoic acid-κO)(4,4′-dimethyl-2,2′-bipyridine-κ2N,N′)hydroxidocopper(II) monohydrate

Abstract

In the structure of the title complex, [Cu(C7H5O2)(OH)(C12H12N2)(C7H6O2)]·H2O, the CuII ion is penta­coordinated in a tetra­gonal-pyramidal geometry with one O atom of a hydroxide group, one O atom of a benzoate anion and two N atoms of a 4,4′-dimethyl-2,2′-bipyridine ligand occupying the basal plane, and one O atom of a benzoic acid mol­ecule located at the apical site. The title complex was refined with a metal-coordinated OH group and a ‘free’ benzoic acid molecule, although it can be assumed that the proton is delocalized between the OH and the COOH group. The uncoordinated water mol­ecule is equally disordered over two positions. The structure displays O—H⋯O hydrogen bonding.
