| Abstract: | Three new coordination polymers, namely, ML(H2O)]n (M = Co (1), Zn (2)) and CuL(DMF)]n (3), have been hydrothermally synthesized through the reaction of bifunctional ligand 5-((2-methyl-1H-imidazol-1-yl)methyl)benzene-1,3-dioic acid (H2L) with divalent cobalt, zinc and copper salts, and structurally characterized by elemental analysis, IR and X-ray diffraction. Both complexes 1 and 2 are two-fold interpenetration 3D frameworks. Complex 3 exhibits (3,6)-connected framework with (4.62)2(42.610.83) topology. Furthermore, UV–vis absorption spectra and powder X-ray diffraction (PXRD) were investigated as well. |
