Abstract: In the title compound, {[Co(1,4-chdc)(L)₂]·H₂O}_n, where 1,4-chdc is the cyclohexane-1,4-dicarboxylate dianion, C₈H₁₀O₄^2-, and L is 2-methyl-1H-imidazole, C₄H₆N₂, each Co^II atom is four-coordinated by two O atoms from two 1,4-chdc ligands and two N atoms from two L molecules in a distorted tetrahedral geometry. Each 1,4-chdc anion acts as a bidentate ligand that links two Co^II atoms, thus generating a helical chain. These chains are decorated with L ligands alternately on the two sides. In addition, O-HO and N-HO hydrogen bonds complete the structure of (I).
