Copper(II) and cobalt(II) complexes of 2,2-diphenyl-4,4,6,6-tetrakis(1-pyrazolyl)cyclotriphosphazene, N3P3Ph2Pz4. X-ray crystal structure of N3P3Ph2Pz4*CoCl2*0.5CH2Cl2

Synthesis and characterization of isotypical compounds N3P3Ph2Pz4*MX2 (M=Cu, X=Cl or Br; M=Co, X=Cl) are reported. The X-ray crystal structure of N3P3Ph2Pz4*CoCl2*0.5CH2Cl2 is described. The structure is a distorted trigonal bipyramid in which the cobalt atom is coordianted by a ligand ,olecule through the two nongeminal pyrazolyl pyridinic nitrogens at the equatorial sites and a cyclophosphazene ring nitrogen at the axial position. The remaining axial and equatorial positions are occupied by the two chlorine atoms.
