合成了题目化合物,并用X射线单晶衍射法测定结构。其晶体学参数:空间群:P_1~-,a=14.118(3)A,b=14.453(3)A,c=16.392(4)A,a=111.60(2)°,β=93.75(2)°,γ=117.10(1)°,V=2656(1)A~3,D_c=1.23g/cm~3,Z=2。4384个衍射点参与修正,最终偏差因子R=0.0707。三个铜原子构成近似的等边三角形,硫原子桥连二个铜原子,每个铜皆是二配位。铜和硫原子交替形成折叠的非共面的Cu_3S_3六员环,Cu-Cu平均距离为2.666A。研究表明,配体a碳上基团的体积愈大,铜原子簇之簇合度愈小。
The title compound was synthesized and its structure was determined by X-ray single crystal diffraction. The crystallographic parameters are as follows: space group: P_1 ~ -, a = 14.118 (3) A, b = 14.453 (3) A, c = 16.392 (4) A, a = 111.60 °, γ = 117.10 (1) °, V = 2656 (1) A ~ 3, D_c = 1.23g / cm ~ 3 and Z = 2.4384 diffraction points. The final deviation factor R = 0.0707. The three copper atoms form an approximate equilateral triangle, and the sulfur atom bridges two copper atoms, each of which is a bidentate one. Copper and sulfur atoms alternately form a folded non-coplanar Cu_3S_3 six-membered ring with an average Cu-Cu distance of 2.666A. The results show that the larger the volume of the group on the carbon of the ligand a, the smaller the cluster degree of copper clusters.
