摘　　要：发展了一种有机膦协助合成法用于制备铜簇合物Cu_(36)H_20(S_2P(OC_3H_7)_2)_(12 )(Cu_(36)).通过单晶X射线衍射分析表明该簇合物的金属框架可以看作核壳结构,内核结构为Cu_(12)空心二十面体,外壳结构为Cu_(24)小斜方截半立方体.与[Cu_(30)H_(18)(S_2P(OC_3H_7)_2)_(12)](Cu_(30))相比较,Cu_(36)的金属框架可看作由Cu_(30)外壳层增加两个Cu_3三角形单元组成,从而证明了铜簇合物间结构的关联性和演变特性.此外,Cu_(36)簇合物可用于合成色胺酮反应的催化剂,当选择碳酸氢钠作为碱,二甲基亚砜作为溶剂,能够取得良好的催化效果.In this study,Cu36H20(S2P(OC3H7)2)12(Cu36)was synthesized based on an organic phosphine mediated method.The metal framework of Cu36 is a core-shell structure according to the result of single-crystal X-ray diffraction.The core structure is a Cu12 hollow icosahedron and the shell structure is a Cu24 rhombicuboctahedron.The metal framework of Cu36 might be evolved from Cu30H18(S2P(OC3H7)2)12(Cu30)when two Cu3 triangles was added to the shell structure Cu30,which indicated the structural correlation existed between different clusters.In addition,Cu36 cluster displayed good catalytic effect for the synthesis of tryptanthrin when dicarbonate and dimethyl sulfoxide were used as base and solvent respectively.
