✦ Synopsis

The title compound, [Ni(C 5 HN 2 O 4 )(C 10 H 8 N 2 )] n , is isotypic with its Co II and Zn II analogues. The asymmetric unit contains two crystallographically independent monomer units with similar geometry. The Ni II cations have a distorted octahedral environment formed by two carboxylate O atoms and by four N atoms, two of which belong to the 2,2 0 -bipyridine ligands and two to different imidazole rings. One imidazole-4,5carboxylate ligand is connected to two Ni II cations, which results in the formation of one-dimensional zigzag chains parallel to [010].
