{6,6′-Dimethoxy-2,2′-[6-bromopyridine-2,3-diylbis(nitrilomethylidyne)]diphenolato}copper(II) methanol solvate

Abstract

In the title compound, [Cu(C21H16BrN3O4)]·CH3OH, the CuII ion is coordinated by two N [Cu—N = 1.814 (3) and 1.917 (3) Å] and two O [Cu—O = 1.805 (3) and 1.893 (3) Å] atoms from the tetradentate Schiff base ligand in a distorted square-planar geometry. In the crystal structure, the approximately planar Cu complex molecules are paired into centrosymmetric dimers with short intermolecular Cu...N distances of 3.162 (3) Å. Weak O---H...O hydrogen bonds may help to stabilize the structure.
