A new salt, [BrBzTPP][CuBr3](1) ([BrBzTPP]+ = 1-(4'-bromobenzyl)triphenylphosphinium), was simply synthesized by the direct reaction of CuBr2 and [BrBzTPP]Br in methanol and characterized by elemental analyses, IR, MS spectra and single crystal X-ray diffraction. The crystal is monoclinic space group, P21/c, a = 9.279(1) angstrom, b = 16.129(2) angstrom, c = 17.545(3) angstrom, = 101.54(1)degrees, V = 2572.7(7) angstrom 3, Z = 4. The Cu(II) ions of the title complex form a dimer with Cu center dot center dot center dot Cu distance of 3.597 angstrom through Cu center dot center dot Br coordination bond, while the [BrBzTPP]+ form a 1D chain by weak C-H center dot center dot center dot hydrogen bond with a H center dot center dot center dot distance of 3.098 angstrom.
