(2,2'-Bipyridine-²N,N')bis(2-bromo-4-carboxylbenzoato-O)copper(II)

A.-Q. Ma, D.-J. Xu and L.-G. Zhu

Abstract: The reaction of copper(II) chloride with 2-bromo-1,4-benzenedicarboxylic acid (H₂bbdc) and 2,2'-bipyridine in aqueous solution under hydrothermal conditions gave the title compound, [Cu(C₈H₄BrO₄)₂(C₁₀H₈N₂)]. The Cu^II atom lies on a twofold axis and is coordinated by two singly deprotonated 2-bromo-1,4-benzenedicarboxylate groups and one 2,2'-bipyridine ligand in a square-planar geometry. Intermolecular O-HO hydrogen bonds between carboxylate groups ensure a two-dimensional architecture with double sheets.
