Conventional usage of TaCl5 in the polymerizable complex (PC) method results in the corrosion of experimental equipment and degradation of functional properties of the obtained materials due to the residual chloride. In this report ammonium and guanidine salts of tantalum-citric acid complex were used as soluble tantalum compounds. Four tantalum containing complex oxides (NaTaO3, SrTa2O6, Sr2Ta2O7 and Sr5Ta4O15) were successfully synthesized by PC method using these chloride-free precursors.
