Insertion of zinc into the cyclophosphazene skeleton: synthesis and structure of six-membered-ring complexes of zinc

Abstract

Cyclozincaphosphazenes have been synthesized by the reaction of the bis-silylated ligand HN[P(NMe2)2NSiMe3]2 (1) with ZnR2 (2) (R = N(SiMe&, Me, Et). These complexes have been characterized by IR, NMR, and mass spectroscopy and by X-ray crystal structural analysis. X-ray analysis of [N(P(NMe2)2NSiMe3]2ZnN(SiMe3)2(]3 ) revealed that it crystallizes as a monomer in the solid state.
