Two N-donor ligands mediated Cd(II) coordination polymers, namely, [Cd(L)(dmpz)(2)](n) (1) and {[Cd(L)(atr)(0.5)(H2O)](H2O)}(n) (2) (H2L = methyl-3-hydroxy-5-carboxy-2-thiophenecarboxylate, dmpz = 3,5-dimethylpyrazole, and atr = 4-amino-l,2,4-triazole), have been produced. Their structures were characterized by single-crystal X-ray diffraction analysis, elemental analyses and infrared spectra. Compound 1 possesses a one-dimensional (1D) chain structure and is finally extended into a three-dimensional (3D) supramolecular architecture though hydrogen bonding interactions. Compound 2 features a two-dimensional (2D) network with 4-connected sql topology based on dinuclear Cd(II) clusters as nodes, which is also assembled into a 3D supramolecular architecture through hydrogen bonding interactions. Furthermore, compounds 1 and 2 exhibit high thermal stabilities and intense fluorescent emission in the solid, and can be explored as potential luminescent materials.
