抄録

The copper(II) complex of the tridentate ligand 4-chloro-3-methyl-6(3′-N,N-dimethylamino-1′-iminomethyl)phenol crystallizes in an orthorhombic space group, Pbca with cell parameters a = 9.1388(8), b = 12.386(2), c = 29.871(3)Å, V = 3381.1(6)Å3, Z = 8, Dcal = 1.479 Mg/m3 and T = 293 K. The structure was refined to the final R = 0.0416 using 2492 observed reflections. The copper atom is penta coordinated with the acetate group coordinating asymmetrically. The local CuN2OO2′ chromophore has a distorted trigonal-bipyramidal stereochemistry and the molecule involves significantly different Cu-ligand bond lengths. The six-membered chelate ring containing the N12 atom assumes chair conformation and C-H…π and C-H…O types of intermolecular interactions play a role in stabilizing the crystal packing in addition to van der Waals forces.
