| Abstract: A Co(Ⅱ) coordination polymer has been synthesized hydrothermally, namely, {[Co(L)(chdc)]2H2O}n (1), (L=1,3-bis-(benzimidazole-1-yl-methylene)-benzene, H2chdc=1,4-cyclohexanedicrboxylic acid). Structure analysis indicates that complex 1 belongs to monoclinic system, space group C2/c, a=1.450 4(1) nm, b=1.834 9(2) nm, c=2.128 7(2) nm, β=94.325(1)°, V=5.649 2(9) nm3, Z=4. Compound 1 exhibits a looped-like chain structure, then the chains are connected into 2D supramolecular structure by interchain π-π satcking interaction. Complex 1 possesses a remarkable activity for degradation of Congo red in a Fenton-like process. CCDC: 892179. |
