Cyclometallacyclophosphazene complexes of titanium(IV) corresponding to [{N(PPh2NR)2}nTiCl4-n], [{N(PPh2NR)2}nTiCl2-n (OPri)2], and [{N(PPh2NR)2}n(OPri) 2-n](R=Ph or SiMe3, G=CH2CH2, n=1 or 2) have been synthesized under anhydrous and inert conditions by the reaction of acyclic bis-silylated phosphazene ligand (A), [HN(PPh2NSiMe3)2], or bis-phenylated phosphazene ligand (B), [HN(PPh2NPh)2] with TiCl4, TiCl2(OPri)2 or (OPri)2 in 1:1 and 2:1 molar ratios. These titanatriazadiphosphorines were characterized by elemental analyses (C, H, N, Cl and Ti), molecular weight determination, and spectral studies including IR and NMR (1H, 13C, and 31P), which have indicated monomeric nature of the complexes and bidentate mode of bonding by phosphazene moiety leading to a trigonal bipyramidal and octahedral geometries around the titanium atom in 5 and 6 coordination numbers.
