Reactions of CuBr with equimolar PyHBr or γ-MePyHBr afforded two novel one-dimensional bromocuprate (Ⅰ)polymers { (PyH)3[Cu3Br6] } ∞ (1) and { (γ-MePyH) 2[Cu2Br4] } ∞ (2), respectively. Both 1 and 2 were charac-terized by IR, elemental analysis, and X-ray crystallography. Crystal data for 1: monoclinic, space group P21 / n,a=0.93262(12) nm, b=1.3497(2) nm, c=1.9149(2) nm, β=93.465(7)°, V=2.4060(5) nm3, Z=4.Crystal data for 2: orthorhombic, space group Pbcm, a =0. 8659(4)nm, b = 1. 5669(6)nm, c = 1. 2849(5)nm,V= 1. 7432(2) nm3, Z =4. The structure of 1 has a unique helical chain composed of [Cu3Br5] units andμ-bromide anions while that of 2 shows a linear chain consisted of [Cu2(μ-Br)2] units bridged by pairs ofμ-Bratoms.
