Abstract
In the title coordination compound, {[Zn(C7H4BrO2)2(C12H10N2)]·CH3CN}n, the ZnII atom is four-coordinated in a distorted tetrahedral environment by two carboxylate O atoms from two different 4-bromobenzoate (bpe) ligands and two N atoms from two symmetry-related 1,2-bis(4-pyridyl)ethene ligands. The ZnII atoms are bridged by the bpe ligands, which lie across centres of inversion, forming a zigzag chain along [001]. The void space of each unit cell is occupied by an acetonitrile solvent molecule, which is connected to the complex molecule by a weak C—H⋯N hydrogen bond.
