Preparation and Crystal Structure of a Phenoxo-Bridged Dinuclear Copper(II) Complex with N-Salicylidene-2-hydroxy-5-bromobenzylamine

Abstract

The title compound, phenoxo-bridged dinuclear copper(II) complex with N-salicylidene-2-hydroxy-5-bromobenzylamine (H₂shbb) [Cu₂(shbb)₂(dmso)₂]·2dmso (dmso = dimethyl sulfoxide), was synthesized and the crystal structure was determined by the single-crystal X-ray diffraction method at 90 K. It crystallizes in the monoclinic space group P2₁/n with a = 16.994(3)Å, b = 8.3932(16)Å, c = 15.755(3)Å, β = 111.547(3)°, V = 2090.2(7)ų, D_x = 1.665 g/cm³, and Z = 2. The R1 and wR2 values are 0.0505 and 0.0649, respectively, for 4759 reflections. The molecule is a phenoxo-bridged dinuclear copper(II) complex having an elongated square-pyramidal coordination geometry with the O₃N basal atoms from the shbb₂^- ligands and the apical O atom from the dmso ligand.
