正丁基黄原酸铜与三苯基膦配合物的结构和表征

Structure and Characterization of (o-Butyldithiocarbonatio-S,S′) bis(triphenylphosphine) Copper(Ⅰ) Complex

合成并通过IR、UV、^1H NMR、TGA及单晶X射线衍射研究了正丁基黄原酸铜与三苯基膦配合物的结构和性能。该配合物属单斜晶系，空间群P21／c，晶胞参数为：n=11．000（2）A，b=20．090（4）A。c=17．320（4）A，β=103.800（3）°，V=3717．1（13）A^3，Z=4。中心铜原子与来自正丁基黄原酸根的两个硫原子及三苯基膦的两个磷原子配位，呈扭曲的四面体构型。IR，UV及^1H NMR分析结果与晶体结构一致。热重分析研究表明该配合物从110％开始分解，到295℃分解完全。留下CuS。

The complex （PPh3）2Cu（S2COBu） was synthesized by the reaction of excessive tfiphenylphosphine and copper（ Ⅱ ） xanthatc, and characterized by using IR, UV and ^1H NMR. The crystal structure of the title compound has been determined by X-ray diffraction. The yellow crystal of the complex is monoelinic of space group P21/c, with parameters a=11.000（2）A, b =20.090（4）A, c = 17.320（4）A, β=103.800（3）°, V=3717.1（13）A^3 and Z = 4. In the complex, the central Cu atom is in a distorted tetrahcdral environment and chelated by two phosphorus atoms from the triphenylphosphine groups and two sulfur atoms from the O-butyldithiocarbonate. IR, UV and ^1H NMR results confirmed the structure. The thermal analytical data indicate that the complex began to decompose at 110℃, and decomposition completed at 295℃, leaving CuS.
