SYNTHESIS OF MINOMETHYL)-PYRIDYLPENTAPHENOXYCYCLOTRIPHOSPHAZENE AND ITS COMPLEX-FORMATION WITH COPPER(II) NITRATE - MOLECULAR-STRUCTURE OF (CU[N3P3(OC6H5)(5)(NHCH2-(3-C5H4N))](2)(NO3)(2))

The reaction of monochloropentaphenoxycyclotriphosphazene with 3-(amin omethyl)pyridine yields aminomethyl)pyridylpentaphenoxycyclotriphospha zene (1), a new N-donor ligand with five nitrogen atoms as potential c oordination centers. Complex formation with copper(II) nitrate yields compound 2 with the general structure Cu(1)(2)(NO3)(2). The X-ray stru cture analysis shows that the copper ion is coordinated by two nitroge n atoms of the pyridine rings and four oxygen atoms of the unsymmetric al bidentate nitrate groups in a Jahn-Teller distorted octahedral arra ngement.
