(L) yields binuclear complexes of the general formula [Cu(PR3)(L)Cl]2 [L = 1,3-thiazolidine-2-thione (tzdtH), benz-1,3- thiazoline-2-thione (bztztH), dithiouracil (dtu), purine-6-thione (pur6SH) and thiourea (tu)]. Irradition of the complexes, in chloroform, methanol and acetonitrile solutions, caused phosphine evolution while the Cu2S2 core remained intact. The crystal structure of [Cu(tptp)(tzdtH)Cl]2
[Cu(PR 3)Cl] 4 [其中PR 3 =三-对甲苯基膦(tptp)或三苯基膦(tpp)]与几种杂环硫酮(L)的反应生成通式为[Cu(PR 3)的双核配合物)(L)Cl] 2 [L = 1,3-噻唑烷-2-硫酮(tzdtH),苯并1,3-噻唑啉-2-硫酮(bztztH),二硫尿嘧啶(dtu),嘌呤-6-硫酮(pur6SH )和硫脲(tu)]。在氯仿,甲醇和乙腈溶液中辐照配合物会导致磷化氢放出,而Cu 2 S 2核保持完好无损。[Cu(tptp)(tzdtH)Cl] 2的晶体结构已通过单晶X射线衍射法确定。在铜2 S 2核的CuS键长为2.386(1)和2.470(1)。CuP和CuCl的距离分别为2.222(1)和2.283(1)。
