Abstract: Reaction of(NH4)2MoOS3 with CuBr and AgBr(molar ratio=1∶4∶1) in α-MePy produced dark red crystals of [MoOS3Cu4(α-MePy)6Br2]. The product was characterized by elemental analysis, IR and X-ray diffraction. It crystallizes in a triclinic system with space group P1 and unit cell parameters a=0.950 9(3) nm, b=1.066 8(2) nm, c=2.153 6(3) nm, α=94.846(9)°, β=92.054(7)°, γ=99.299(8)°, V=2.145 5(8) nm3, Z=2, D c=1.828 g·cm-3, F(000)=1 168, μ=42.79 cm-1, R=0.049 and Rw=0.051. The compound consists of a nido-shaped MoS3Cu3 cluster unit and a four-membered CuBrCuS ring by sharing the same Cu3—S3 bond. The Mo atom and the four Cu atoms adopt a distorted tetrahedral geometry coordination. The Mo…Cu1, Mo…Cu2 and Mo…Cu3 distances are 0.271 1(3), 0 269 8(2), and 0.268 1(1) nm, respectively.
