| Abstract: | Self-assembly of CoSO4 salt and 2-(p-isopropylphenyl)-1H-imidazole-4,5-dicarboxylic acid (H3PPhIDC), results in the formation of a metal-organic framework, [Co(HPPhIDC)(CH3OH)]n (1), which has been characterized by elemental analysis, IR, X-ray powder diffraction (XRPD), thermogravimetric analysis and single-crystal X-ray diffraction. Polymer 1 is a meso-compound and displays a (3,3)-connected 3D structure with 1D channels and cages, which are composed of left- and right-handed helices pillared by Co2 + linkers. Moreover, the antiferromagnetic coupling between the neighboring Co(II) ions in 1 can be observed. |
