Inorganic Coordination Polymers, VII. Zinc(II) Dimethyl-, Methylphenyl-, and Diphenylphosphinates.

摘要

Zinc dimethyl-, methylphenyl-, and diphenylphosphinate were prepared by the reaction of Zn(C2H3O2).2H2O with the appropriate acid or salt and found to exist in amorphous and crystalline forms. Zinc methylphenyl- phosphinate, the most tactable, exhibits many of the physical attributes of polymeric materials, both in solution and bulk form, supporting our earlier suggestion that these compounds are double-bridged coordination polymers. Thermogravimetric analysis indicates initial decomposition temperatures of 440, 425, and 490 C., respectively, for the three polymers, but long-term studies show initiation of decomposition at somewhat lower temperatures.
