Abstract : The invention relates generally to the preparation of inorganic coordination polymers and in particular to the preparation of tantalum phosphinates. The preparation thereof is based on the reaction of a tantalum pentavalent compound (TaZ5) with a phosphinic acid (RR'P(O)OH) in a dry inert solvent at reflux temperatures. Z may be a halo, alkoxy, or aryloxy group or a mixture thereof; R and R' arc aryl groups. Such compounds are useful in high temperature laminates as fillers. Oxide hydrates of these compounds may be prepared by hydrolysis and are similarly useful in high temperature laminates as fillers.
