Abstract
The reaction of the acyclic phosphazene ligand, HNP(NMe2)2NSiMe32 (1) with NH4VO3 in 1:1 molar ratio resulted in the formation of an ionic species NP(NMe2)2NH2+2 VO4(SiMe3)2- (2) in quantitative yield. The reaction shows the migration of silyl group from the terminal nitrogen atoms of the phosphazene ligand 1 to the oxygen of the vanadyl group. Compound 2 crystallizes as monomer in the solid state. The X-ray structure of the phosphazenium salt, NP(NMe2)2NH2+2Cl- (3) has also been described which crystallizes as a polymeric zig-zag chain in the solid state.
