仲丁氧基二硫代甲酸铜与三苯基膦配合物

Complex of (O-sec.-Butyldithiocarbonatio-S,S') Copper (Ⅰ) and Triphenylphosphine

该文研究黄原酸过渡金属盐配合物的合成及其晶体结构。采用溶剂法制备了仲丁氧基二硫代甲酸铜与三苯基膦的配合物,挥发法培养出单晶。通过元素分析、FT—IR、1HNMR对其进行表征。单晶X射线衍射测定的晶体结构表明铜原子为四配位,分别与黄原酸根的两个硫原子及三苯基膦的两个磷原子配位。热分析研究表明:该配合物从2 10℃开始分解,到2 4 0℃分解结束,失重率为87.6 %。剩余产物为Cu2 S ,证明单晶中铜为一价。

The synthesis of transitional metal xanthates and their single crystal structures were studied. The complex of (O-sec.-butyldithiocarbonatio-S,S') copper (Ⅰ) with triphenylphosphine was synthesized by solvation and its single crystal was obtained by evolution. The complex was characterized by elementary analysis ,FT-IR and 1HNMR. The crystal structure was determined by single crystal X-ray diffraction. The Cu atom is four-coordination, and it is coordinated by two sulfur atoms from xanthate salt and two phosphorus atoms from triphenylphosphine.Thermograri-metric analysis showed that the complex decomposed from 210 ℃ to 240 ℃. The rate of weightlessness was 87.6 %. The surplus matter was Cu 2S, which proved the copper atom in the single crystal was one valence.
