Three Cd(II)-based coordination polymers (CPs) with unique structures and topologies, namely, [Cd₂(L)₂(bimb)₂(H₂O)₂]_n (1), {[Cd(L)(bmib)_0.5(H₂O)](CH₃OH)_0.5}_n (2) and [Cd(L)(beib)_0.5(H₂O)]_n (3) (H₂L = methyl-3-hydroxy-5-carboxy-2-thiophenecarboxylate, bimb = 1,4-bis(imidazol-1′-yl)butane, bmib = 1,4-bis(2-methylimidazolyl)butane and beib = 1,4-bis(2-ethylimidazolyl)butane) have been successfully constructed and characterized by single crystal X-ray structure determination, IR spectra, elemental analyses and powder X-ray diffractions. X-ray results showed compound 1 features a new 2-nodal 5,6-connected 3D network with a point symbol of {4⁵.5.6³.7}₂{4².5⁴.6⁹}. Compound 2 exhibits a rare 6-fold interpenetrating dia 3D network. Compound 3 bears a hydrogen bonded-extended 3D supramolecular structure based upon sql layers assembled from dinuclear Cd(II) units. Thermal stability and solid photoluminescence properties of compounds 1–3 were studied. Significantly, compound 1 can sense nitrobenzene through the luminescence quenching effect.
