Q. Chen, W. Feng, X. Zheng and Y. Xu

Abstract: The crystal structure of the title compound, [CuCl(C₆H₅O₂)]_n, exhibits polymeric chains extended in the b-axis direction, with a shortest CuCu distance of 2.885 (2) Å. The Cu atom is tetrahedrally coordinated by three Cl atoms, each of which bridges three metal atoms, and the N atom of isonicotinic acid. The Cu and Cl atoms lie on mirror planes, across which the isonicotinic acid ligands are disordered. Each Cu₂Cl₂ ring is centrosymmetric. The carboxyl groups are connected by O-HO hydrogen bonds into an infinite chain running in the [101] direction. The Cu-Cl bond distances are 2.343 (1) and 2.483 (2) Å, while Cu-N is 1.976 (5) Å.
