The solubility of Gd Cl3 · 3H2 O- 1 8C6-CH3 COCH3 ternary system (2 5 ℃) was studied by semi-micro phase equilibria method, and the refractive index of each saturated solution was measured.The results showed that two stoichiometry New Complexes: 2 Gd Cl3 · 1 8C6 · 6H2O · CH3 COCH3 () and Gd Cl3 · 1 8C6 · 6H2 O · 0.5 CH3COCH3 (), both of which are solid-liquid heterospecific complexes. The effects of salt anions and solvents on the formation of complexes were discussed. The behavior of water during phase equilibrium was investigated, and the amount of n (H 2 O) / n (Gd Cl 3) species in both the liquid phase and the solid phase The ratio is always 3: 1.According to the phase diagram data, solid complexes were prepared, and the chemical compositions, IR, DTG, TG and DSC were used to study the composition and properties of the solid complexes.
