Abstract: The solubility properties of the title syste MAt 30 in the whole concentration range have been systematically investigated by phase equilibrium method. The results indicated that there is a ternary complex, which is incongruently soluble in water, formed in the system:Yb(BAPHDCA)2(ClO4)34H2O. Under the direction of phase equilibrium results, the complex has been prepared and characterized by chemical and elemental analysis, IRspectra, TG-DTG and X-ray powder diffraction.
