The title compound, catena-poly[[bromocopper(II)]-mu-(quinolin-8-yloxy)acetato-kappa(4)N,O,O':O''], CuBr(C(11)H(8)NO(3)), is a novel carboxylate-bridged one-dimensional helical copper(II) polymer. The metal ion exhibits an approximately square-pyramidal CuBrNO(3) coordination environment, with the three donor atoms of the ligand and the bromide ion occupying the basal positions, and an O atom belonging to the carboxylate group of an adjacent molecule in the apical site. Carboxylate groups are mutually cis oriented, and each anti-anti carboxylate group bridges two copper(II) ions via one apical and one basal position [Cu...Cu = 5.677 (1) A], resulting in the formation of a helical chain along the crystallographic b axis.
标题化合物，链状聚[[溴化铜（II）]-μ-（喹啉-8-基氧基）乙酸根-κ(4)N,O,O':O'']，[CuBr(C₁₁H₈NO₃)]ₙ，是一种新型的羧酸根桥连的一维螺旋状铜（II）聚合物。金属离子呈现出近似四方锥的CuBrNO₃配位环境，配体的三个供体原子和溴离子占据底面位置，而一个属于相邻分子羧酸根基团的O原子位于顶端位置。羧酸根基团相互呈顺式取向，每个反-反羧酸根基团通过一个顶端位置和一个底面位置桥连两个铜（II）离子[Cu...Cu = 5.677 (1) Å]，从而沿着晶体学b轴形成螺旋链。
