A Cd(Ⅱ) complex, [Cd(L)2(H20)]n (1), based on benzimidazole-5-carboxylic acid (HL) ligand has been hydrothermally synthesized. The Cd(Ⅱ) atoms have a distorted octahedron coordination geometry. Each L ligand links two Cd(Ⅱ) atoms and each Cd(Ⅱ) atom attaches to four L ligands to form a two-dimensional (2D) layer structure along bc plane, which consists of regular parallelograms, then yield a three-dimensional (3D) supramolecular network by N-H..-O and O-H...O hydrogen bonds. The TGA and luminescence property in solid state of complex 1 have been further studied and discussed in this paper. CCDC: 722775.
