Two tetrabromocuprate (II) salts with substituted benzyl pyridinium, [BzPy]2[CuBr4](1) and [4NO2BzPy]2[CuBr4](2) ([BzPy]+ = 1-benzylpyridinium; [4NO2BzPy]+ = 1-(4'-nitrobenzy- lpyridinium), were synthesized and characterized by elemental analysis, IR, MS, and single-crystal X-ray diffraction. The two salts comprise a [CuBr4]2-anion and two cations, and the [CuBr4]2-anion exhibits a distorted tetrahedral coordination geometry. The weak interactions such as p..., ..., C-H..., C-H...Br or C-H...O hydrogen bonds play important roles in the stacking and stabilization of the two salts, and give rise to a 3D network structure. In addition, the two salts show good antibacterial activities for colibacillus, aurococcus, bacillus subtilus and bacillus thuringiensis.
