Crystal structure of μ-phenoxo bridged dicopper complex: {N-[(2-hydroxylato-5-methyl)benzyl-(2’-hydroxylato-3’,5’-dimethylbenzyl)]ethyl amine dicopper(II)}

The title compound crystallizes in monoclinic space group C2/c with cell parameters a = 21.404(2), b = 13.962(1), c = 17.917(1)Å, β = 124.394(2)°, V = 4418.3(6)Å3, Z = 8, Dcal = 1.193Mg/m3 and T = 293 K. The structure was solved by Patterson method and refined by full-matrix least-squares procedures to final R = 0.0882 using 5253 observed reflections. The tetra coordinated copper atom have a slight distorted square planar geometry with the Cu-Cu distance of 2.987(1)Å. The two six membered rings containing copper atom assume distorted sofa conformation. C-H… π and C-H…O type of intermolecular interactions play a role in stabilizing the crystal packing in addition to van der Waals forces.

Keywords: μ-phenoxo bridged dicopper complexes, structure, conformation, C-H…pi interaction, hydrogen bonds
