Rapid synthesis of a novel cadmium imidazole-4,5-dicarboxylate metal–organic framework under microwave-assisted solvothermal condition

A novel three-dimensional (3D) coordination polymer, [Cd(μ3-HIDC)(bbi)0.5]n (1) (H3IDC = 4,5-imidazoledicarboxylic acid, bbi = 1,1’-(1,4-butanediyl)bis(imidazole)), has been synthesized under microwave heating solvothermal conditions and characterized by elemental analysis, IR, TG, and single crystal X-ray diffraction. The crystal structure reveal that compound 1 consists of 2D brickwall-like networks of [Cd(μ3-HIDC)]n, which are further linked through μ2-bbi to generate a 3D structure. Compound 1 is stable up to 330 °C and displays strong blue fluorescent emission at room temperature. This work demonstrates that microwave-assisted solvothermal synthesis method is an efficient and fast way to prepare metal coordination polymers.
