以1,2-双(二苯基膦)乙烷(dppe)、1,4-双(二苯基膦)丁烷(dppb)和卤化亚铜作为初始原料,合成得到1个三核铜(I)溴化物[{Cu2(μ-dppe)(μ-Br)2}(μ-dppe)2CuBr](1)和1个双核铜(I)碘化物[{Cu(dppb)I}2(μ-dppb)](2). X-射线单晶衍射表明:配合物1为三核铜配合物,Cu1和Cu2两原子采用常见的四配位方式,分别与2个Br原子和2个P原子连接构成1个变型四面体,而Cu3原子采取三配位模式,与1个Br和2个P原子相连接形成1个平面三角形, Cu1、Cu2和Cu3这3个铜原子又共同构成了1个近似等腰的平面三角形;配合物2为双核铜配合物,3个dppb配体表现出2种配位方式:2个以二齿螯合方式分别与1个Cu原子连接,1个以桥联方式与2个相同的{Cu(dppb)I}砌块相连接.

Utilizing 1,2-bis(diphenylphosphino)ethane (dppe), 1,4-bis(diphenylphosphino)butane (dppb), and cuprous halide as the starting materials, a trinuclear copper (I) bromide complex [{Cu 2 (μ-dppe)(μ-Br)2}(μ-dppe)2CuBr] (1) and a binuclear copper(I) iodide complex [{Cu(dppb)I}2 (μ-dppb)] (2) were synthesized and structurally characterized. As revealed by single-crystal X-ray diffraction, compound 1 is a trinuclear copper(I) complex in which the Cu1 and Cu2 atoms adopt a common four-coordinate mode. Each connects with two bromide and two phosphorus atoms, respectively, forming a distorted tetrahedral configuration. The Cu3 atom is trigonally coordinated via two phosphorus and one bromide atoms by generating a plane triangle. These three copper(I) atoms (Cu1, Cu2, Cu3) give a nearly isosceles triangle together. Compound 2 is a binuclear Cu(I) complex, in which these three dppb ligands offer two kinds of coordination fashions:two of them are chelating, one for each copper atom. However, the third one acts as a bridge assembling two same {Cu (dppb)I} moieties into a copper(I) dimer.
