“…A basic design route for this kind of polymer is the self-assembly of suitably designed organic ligands with metal ions. Since flexible N-containing ligands can adopt different conformations according to the coordination requirements of the different metal centers [6][7][8][9][10][11], we and other groups have focused on the synthesis and structural exploration of coordination polymers with such ligands [12][13][14][15][16][17][18][19][20][21][22][23][24][25]. The flexible 1,1 0 -(1,4-butanediyl)bis(benzimidazole) (bbbm) not only possesses the merits of benzimidazole as a ligand but also can freely bend and rotate to coordinate to metals.…”

Two new cobalt(II) coordination polymers, namely [Co 1.5 (PhCOO) 3 (bbbm) 1.5 (H 2 O)] n (1) and [Co(chdc)-(bbbm)] n (2) (bbbm = 1,1 0 -(1,4-butanediyl)bis-1H-benzimidazole, H 2 chdc = 1,4-cyclohexanedicarboxylic acid), have been synthesized and structurally characterized by single crystal X-ray diffraction. The cobalt(II) centers display different environments, with trigonal-bipyramidal and octahedral geometries in 1 and a tetrahedral geometry in 2. The 1D linear chains of complex 1 and ladder-like chains of complex 2 are bridged by bbbm in bis-monodentate coordination mode; the variation of the carboxylate co-ligand effectively tunes the resulting framework architecture. The degradation of methyl orange in a photochemical Fenton-like process using complexes 1 and 2 as catalysts was investigated.

“…To the best of our knowledge, coordination polymers based on flexible bis (5,6-dimethybenzimidazole) and multicarboxylic acid ligands have only been scarcely studied [14][15][16]. In this report, we focus our continuing efforts on coordination polymers based on flexible bis(5,6-dimethybenzimidazole) ligands [17][18][19][20]; here we report the preparation, crystal structure, and fluorescence properties of a new two-dimensional frame-…”

A new 2D cobalt(II) coordination polymers namely {[Co 2 (btec)(L) 2 ]⋅4H 2 O} n (1), where btec = = 1,2,4,5-benzenetetracarboxylate and L = 1,3-bis(5,6-dimethylbenzimidazol-l-yl)-2-propanol, are hydrothermally synthesized and characterized by elemental analyses, IR spectroscopy, and single crystal X-ray diffraction analyses. The structure analysis indicates that the compound belongs to the triclinic system, space group Pī, a = 12.198(2)The complex possesses a binodal (3,4)-connected two-dimensional layered structure bridged by btec and L ligands. The fluorescence and catalytic properties of the complex are also investigated.

Two novel zinc coordination polymers {[Zn(PhCOO)2(bmix)]}n 1 and {[Zn(ada)(bmix)]·(H2O)2}n 2 (bmix = 1,4‐bis(2‐methylimidazole‐1‐ylmethyl)benzene, H2ada = adipic acid), were obtained by the hydrothermal reactions of bmix and zinc acetate with two carboxylate anions, respectively. Structural analyses show that complex 1 possess a one‐dimensional helix chain structure, 2 takes two‐dimensional corrugated (4,4) layer motif. The structural differences of two complexes indicate that organic carboxylate anions play important roles in the formation of such zinc(II) coordination architectures.
