Poly[[[μ‐1,1′‐(butane‐1,4‐diyl)diimidazole‐κ2N:N′](μ‐cyclohexane‐1,4‐dicarboxylato‐κ4O1,O1′:O4,O4′)cadmium(II)] hemihydrate]: a parallel interpenetrating two‐dimensional (4,4) network

In the title coordination compound, {Cd(C₈H₁₀O₄)(C₁₀H₁₄N₄)]·0.5H₂O}_n, the 1,1′‐(butane‐1,4‐diyl)diimidazole ligand and the cyclohexane‐1,4‐dicarboxylate dianion both function in a bridging mode to link adjacent cadmium(II) centers into a two‐dimensional four‐connected (4,4) network. The networks are parallel to the (001) plane. Two (4,4) networks are interpenetrated in an unusual parallel mode. The compound is the first two‐dimensional parallel interpenetrating (4,4) network structure based on a flexible dicarboxylate and a long bidentate N‐donor ligand. The interpenetrating nets are further consolidated by water–carboxylate O—H...O hydrogen bonds.
