COPPER(II) AND COBALT(II) COMPLEXES OF -4,4,6,6-TETRAKIS(1-PYRAZOLYL)CYCLOTRIPHOSPHAZENE, N(3)P(3)PH(2)PZ(4) - X-RAY CRYSTAL-STRUCTURE OF H(2)PZ(4)CENTER-DOT-COCL2-CENTER-DOT-0.5CH(2)CL(2)

Synthesis and characterization of isotypical compounds N(3)P(3)Ph(2)Pz (4) . MX(2) (M = Cu, X = Cl or Br; M = Co, X = Cl) are reported. The X -ray crystal structure of N(3)P(3)Ph(2)Pz(4) . CoCl2 . 0.5CH(2)Cl(2) i s described. The structure is a distorted trigonal bipyramid in which the cobalt atom is coordinated by a ligand molecule through the two no ngeminal pyrazolyl pyridinic nitrogens at the equatorial sites and a c yclophosphazene ring nitrogen at the axial position. The remaining axi al and equatorial positions are occupied by the two chlorine atoms.
