A NEW 2D COBALT(II) COORDINATION POLYMER CONSTRUCTED FROM 1,2,4,5-BENZENETETRACARBOXYLATE AND FLEXIBLE bis(BENZIMIDAZOLE) LIGANDS

Abstract

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.
