| Abstract: 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 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.
