Abstract: 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.
