N2 - Three coordination polymers, i.e. [Co(HL)(HBDC)]n (1), [Co(HL)(BDC)0.5]n (2) and {[Zn2(H 2L)(BTC)2](H4L)(H2O) 2}n (3) (L = 2, 2′-(ethanediyl)bis(1H-benzimidazole) , H2BDC = 1, 4-benzenedicarboxylic acid, H3BTC = 1, 3, 5-benzene tricarboxylic acid), have been synthesized under hydrothermal conditions based on bis(2-benzimidazole) and two multi-dentate carboxylate ligands, with different metal ions such as ZnII and CoII. The structures of these coordination polymers have been determined by X-ray single-crystal diffraction. The diverse coordination modes of the H2L ligand and the varying geometries of multi-dentate carboxylate ligands play an important role in the construction of coordination polymers. Various assembly patterns have been observed, including one-dimensional (1D) chain (1), two-dimensional (2D) 3-connected network structure with honeycomb topology (2), and three-dimensional (3D) 3,4-connected porous structure with (6 3)(65,8) topology (3). Thermal analyses of the three polymers have been performed and discussed. Furthermore, strong room temperature photoluminescence of compound 3 was observed.
