摘要：
The crystal structures of 2-methylbenzimidazolium tetrahalocuprates (H2-mebz)2[CuX4] (X = Cl and Br) have been detemined. The chloride salt is monoclinic, P21/c, with a = 8.540(2) Å, b = 16.591(2) Å, c = 14.303(3) Å, and β = 98.69(2)°. The bromide salt is also monoclinic, P21/c, with a = 8.316(3) Å, b = 17.436(3) Å, c = 14.747(3) Å, and β = 98.82(3)°. Both the compounds contain discrete distorted tetrahedral CuX42− anions and almost planar 2-methylbenzimidazolium cations. In the chloride salt, three chloride ions are involved in hydrogen bonding instead of two bromide ions in the bromide salt.
