Tetrakis{μ-1-[2-(2-oxidoethyl­amino)­ethyl­imino­methyl]-2-naphtholato}tetrazinc(II).

The title compound, [Zn4(C15H16N2O2)4], is a novel tetranuclear zinc(II) complex with crystallographic fourfold inversion–rotation symmetry. Each ZnII atom has a distorted square-pyramidal coordination geometry. In the basal plane, the Zn atom is coordinated by two N atoms and two O atoms of one Schiff base ligand. The apical position is occupied by an O atom of another Schiff base ligand. The four Zn atoms in the complex are linked through four bridging O atoms, forming an eight-membered ring.
