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 TaOPC6H52OO2-H2O, whereas in TaOPC6H52O2O32-XH2O and TaOPC6H52O3O-XH2O they have a variety of coordination modes. The thermal stabilities of tantalum diphenylphosphinate dioxide and tantalum bisdiphenylphosphinate sesquioxide were considerably greater than tantalum trisdiphenylphosphinate oxide. Author
