Inorganic Coordination Polymers. XVII. The Preparation and Properties of Tantalum(V) Diphenylphosphinates.

Abstract

Tantalum diphenylphosphinate alkoxides and oxides were prepared with one, two, and three diphenylphosphinate groups per tantalum. They were found to be low molecular weight polymers in solution. The infrared spectra of the tantalum diphenylphosphinate oxides indicate that the phosphinate groups have predominately one mode of coordination (probably symmetrical bridging) in Ta(OP(C6H5)2O)O2-H2O, whereas in Ta(OP(C6H5)2O)2O3/2-XH2O and Ta(OP(C6H5)2O)3O-XH2O they have a variety of coordination modes. The thermal stabilities of tantalum diphenylphosphinate dioxide and tantalum bis(diphenylphosphinate) sesquioxide were considerably greater than tantalum tris(diphenylphosphinate) oxide. (Author)
