Inorganic Coordination Polymers. XIV. Chromium(III) Phosphinate Perfluorocarboxylate Polymers.
Abstract
A series of polymers (Cr(OH)(OPRR'O)(OOC(CF2)(n)CF(CF3)2)) has been prepared and studied. The polymers with R=R'=C6H5 are soluble in CCl2FCClF2, whereas those with R=CH3 and R'=C6H5 and with R=R'=C8H17 are insoluble in all solvents. Attempts to prepare similar materials without hydroxyl groups gave the polymers (Cr(OH)(r)(OPRR'O)(p)(OOC(CF2)(n)CF(CF3)2)(g))(x) with 0 < r < 1. The latter polymers are much more tractable than the former; however they are also less thermally stable. The perfluorocarboxylate groups in these materials can either be chelating or bridging depending on the other ligands present. (Author)
