Abstract

The reaction of [CuCl2L][L = 2,2′-bipyridyl (bipy) or ethylenediamine (en)] with sodium phenoxide in tetrahydrofuran yields the extremely moisture-sensitive diphenoxo-derivatives [Cu(OPh)2(bipy)](1) and [Cu(OPh)2(en)]·PhOH (2). The reaction of CuX (X = Cl or Br) with p-benzoquinone in pyridine gives the diamagnetic adducts [CuX(py)]2·C6H4O2(3); i.r. data suggest that (3) are olefin complexes.

Abstract

The title compound has been shown by X-ray diffraction methods to be a centrosymmetric phenoxo-bridged dimer with terminal phenoxo- and ethylenediamine groups and hydrogen-bonded phenol molecules. The crystals are monoclinic, space group P21/n, and the unit cell has dimensions a= 19.000(13), b= 10.930(9), c= 8.968(5)A, β= 89.90(2)°, U= 1 862.4 A3, and Z= 4. The structure was refined by three-dimensional Patterson and Fourier techniques up to a conventional R value of 0.0437. The copper atoms are five-co-ordinate and the co-ordination geometry is that of a distorted square pyramid. The Cu ⋯ Cu distance is 3.215 A. The compound has a nearly normal magnetic moment at room temperature and the results of the present investigation are discussed in connection with the known magnetic and structural data for dimeric oxygen-bridged copper(II) complexes.
