Abstract: The phase equilibrium of the ternary system La(ClO4)3BAPOAPH2Oat 30 ℃ was studied by means of the isothermal solubility method. The incongruent compound, La2(BAPOAP)3(ClO4)6, was discovered. Based on the results of phase equilibrium, the series compounds Ln2(BAPOAP)3(ClO4)6 were synthesized and characterized by chemical analyses, elemental analyses, IRspectra and TGDTGanalyses.
