Reactions of CuBr with equimolar PyHBr orγMePyHBr afforded two novel one dimensional bromocuprate?polymers{(PyH)_(3)[Cu_(3)Br_(6)]}_(∞)(1)and{(γMePyH)_(2)[Cu_(2)Br_(4)]}_(∞)(2),respectively.Both 1 and 2 were characterized by IR,elemental analysis,and X ray crystallography.Crystal data for 1:monoclinic,space group P2_(1)/n,a=0.93262(12)nm,b=1.3497(2)nm,c=1.9149(2)nm,β=93.465(7)°,V=2.4060(5)nm^(3),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)nm^(3),Z=4.The structure of 1 has a unique helical chain composed of units andμbromide anions while that of 2 shows a linear chain consisted of[Cu_(2)(μBr)_(2)]units bridged by pairs ofμBr atoms.CCDC:1,208412;2,208413. 展开更多
