title: Synthesis and Structural Characterization of P-Functionalized Metallacyclophosphazenes.
abstract: A facile, high-yield synthesis of Cl(3)VNSiMe(3) (1) is reported. 1 and the metal nitride halides Cl(3)MoN and Cl(3)WN react with [{(Me(2)N)(2)PNH(2)}(2)N](+)Cl(-) to form the six-membered metallacyclophosphazenes [(Me(2)N)(2)PN](2)VCl(2) (2), [(Me(2)N)(2)PN](2)MoCl(3).MeCN (3), and [(Me(2)N)(2)PN](2)WCl(3).MeCN (4), respectively. The X-ray structure determinations of 2 and 3 show the compounds to have planar six-membered rings of distorted geometry.
