在干燥氮气氛中 ,以 5 苯基吡唑啉二硫代甲酸钠和无水稀土氯化物为原料 ,乙腈为溶剂 ,制备出稀土与 5 苯基吡唑啉二硫代甲酸形成的 9个新型固态配合物 ,产率达 40 %以上。经元素分析、红外光谱、差热 热重分析和电导测定 ,确定其组成为 :Na[RE(S2 CNC9H9N) 4·xH2 O](RE =La～Dy ,Y ,除Ce和Pm外 ) ,配体是通过两个硫原子以双齿形式与稀土离子配位。热分析表明 ,配合物开始分解温度均低于配体的分解温度 ,说明配合物的热稳定性不如配体。配合物的乙腈溶液 (浓度为 1 2 4～ 1 32× 10 - 3mol·dm- 3)的摩尔电导值在 86～ 10 4Ω- 1 ·cm- 2 ·mol- 1 范围 ,配合物为 1∶1型电解质
In a dry nitrogen atmosphere, 5 phenylpyrazoline dithiocarboxylic acid sodium and anhydrous rare earth chloride as raw materials, acetonitrile as solvent, prepared rare earth and 5 phenylpyrazoline dithioformic acid formed nine new solid Complex, the yield of 40% or more. The composition of Na [RE (S2NC9H9N) 4 · xH2O] (RE = La ~ Dy, Y, with the exception of Ce and Pm) was determined by elemental analysis, IR, TG- The body is bidentate with two rare earth ions through two sulfur atoms. Thermal analysis shows that the decomposition temperature of the complex is lower than the decomposition temperature of the ligand, indicating that the thermal stability of the complex is inferior to that of the ligand. The molar conductivity of the complex in acetonitrile solution (concentration of 1 2 4 ~ 1 32 × 10 -3 mol · dm -3) was in the range of 86 ~ 10 4 Ω -1 · cm -2 · mol -1, the complex was 1: 1 Electrolytes
