Bis[2,4-di-bromo-6-(N-{4-[(E)-1-(benzyl-oxy-imino)-eth-yl]phen-yl}carboximido-yl)phenolato]copper(II)

Abstract

In the title complex, [Cu(C22H17Br2N2O2)2], the Cu(II) ion is four-coordinated in a trans-CuN2O2 square-planar geometry by two phenolate O and two imino N atoms from two deprotonated N,O-bidentate ligands. In the crystal, the packing of the mol-ecules is controlled by C-H⋯π and π-π inter-actions [centroid-centroid distances = 3.568 (3), 3.678 (2), 3.717 (3) and 3.799 (2) Å] and weak Br⋯Br halogen bonds [3.508 (4) Å], linking the mol-ecules into an infinite three-dimensional supra-molecular network.
