Abstract

In the title compound, {[Cu(1,4‐chdc)(L)2]·H2O}n, where 1,4‐chdc is the 1,4‐cyclohexanedicarboxylate dianion, C8H10O42−, and L is 2‐methyl‐1H‐imidazole, C4H6N2, each CuII atom is four‐coordinated by two N atoms from two L ligands and two O atoms from two 1,4‐chdc anions in a distorted tetrahedral geometry. Each 1,4‐chdc ligand bridges two neighbouring CuII atoms in a bidentate mode, forming a unique helical chain. These chains are decorated with L ligands alternately on the two sides. O—H...O and N—H...O hydrogen bonds complete the structure.
