INORGANIC COORDINATION POLYMERS. VIII. COBALT(II) AND ZINC(II) PHOSPHINATE POLYMERS AND COPOLYMERS.
Abstract
The preparation, properties, X-ray powder patterns, and TGA curves are given for cobalt(II) dimethyl-, methylphenyl-, and diphenylphosphinate. The polymeric character of cobalt(II) methylphenylphosphinate is demonstrated by its colligative properties and melt indexes. These cobalt(II) phosphinates along with hybrid copolymers of zinc(II) or cobalt(II) were prepared by the reaction of the metal acetate with the appropriate phosphinic acid or mixture of phosphinic acids. A consideration of the hybrid copolymers leads to the conclusion that both the zinc(II) and cobalt(II) dimethyl- and diphenylphosphinates are likewise polymeric. Thermal stability is discussed in terms of the structures suggested, and it is shown that crystallinity is related to polymer symmetry. (Author)
