摘要

A series of mixed-ligand copper(II) chelates containing the anion of 2-hydroxyaryloxime(oxime) and N,N-disubstituted dithiocarbamate(dtc), Cu(dtc)(oxime), was prepared and characterised. The spectra (IR, ESR, electronic excitation) indicate that the CuNOS2 chromophore attains square planar geometry. The ESR observables suggest appreciable covalency. In the case of Cu(Et(2)dtc)(oxime) chelates, however, the observed data suggest distortion from square planar arrangement to a square pyramidal, indicative of a possible dimerism. In addition, the structure of the trans-bispropanone, 1-(2-hydroxyphenyl)-oximatocopper(II), Cu(C9H10NO2)(2) was determined by X-ray diffraction (monoclinic, space group P2(1)/n, a=12.072(7) Angstrom, b=5.204(2) Angstrom, c=13.571(6) Angstrom, beta=103.72(1)degrees, Z=2). The molecule consists of discrete Cu(ppox)(2) monomeric units, where the Cu atom is in the equatorial plane bonded to two nitrogen atoms and two oxygen at distances of 1.949(2) and 1.882(2) Angstrom, respectively.
