Reactions of CuBr with equimolar PyHBr or γ MePyHBr afforded two novel one dimensional bromocuprate? polymers {(PyH)3}∞ (1) and {(γ MePyH)2}∞ (2), respectively. Both 1 and 2 were characterized 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 units and μ bromide anions while that of 2 shows a linear chain consisted of [Cu2(μ Br)2] units bridged by pairs of μ Br atoms.
