摘要
(NH_4)_2MoS_4、CuBr和(C_(16)H_(33))C_5H_5NBr·H_2O固相反应产物,经CH_2Cl_2/CH_3OH处理得黄色菱形晶体[C_5H_5N(C_(16)H_(33)]_4[Cu_4Br_8],晶体属三斜晶系,空间群为P1,a=0.9762(2)nm,b=3.1948(4)nm,c=0.9143(2)nm,α=94.71(1)°,β=116.48(2)°,γ=92.54(1)°Z=1.晶体中含以Br^-为桥基连接的四核铜(Ⅰ)链状阴离子,四配位铜原子的Cu—Br平均距离为0.2664nm,三配位的钢原子的Cu—Br的平均距离为0.2517nm,铜原子间的距离为0.296～0.320nm.
A dark solid was obtained by the solid state reaction of (NH4)2MoS4, CuBr and [C16H33)C5H5NBr.H2O. The solid was treated with CH2Cl2 and then diffused with CH3OH to produce the yellow single crystal [C5H5N(C16H33)]]4[Cu4Br8]. The crystal is triclinic with a = 0.9762(2) nm, b=3. 1948(4) nm, c=0. 9143(2) nm;a= 94. 71 (1)°,β= 116. 48(2)°, γ = 92. 54(1)°,space group P1, Z= 1. The title compound is a chain-like one of four copper atoms bridged by Br atoms. The average Cu-Br distances of the four-coordinated coppers and the three-coordinated coppers are 0.2664(2) nm and 0.2517(2) nm, respectively. The distance between copper atoms in[Cu4Br8]2-ranges from 0. 2956(3) to 0. 3202(3) nm.
