Abstract: In the title coordination polymer, {[Ni(C₈H₁₀O₄)(C₁₀H₁₄N₄)]·0.25H₂O}_n, the coordination of the Ni^II ion is distorted octahedral. The 1,1'-(butane-1,4-diyl)diimidazole ligand and the cyclohexane-1,4-dicarboxylate dianion bridge metal centres, forming a two-dimensional (4,4) network. The network is consolidated by O-HO hydrogen bonds between the statistically occupied water molecules and O atoms of the two carboxylate groups.
