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(mu(3)-HIDC)(bbi))(0.5)](n) (1) (H3IDC = 4,5-imidazol-edicarboxylic 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(mu(3)-HIDC)](n), which are further linked through mu(2)-bbi to generate a 3D structure. Compound 1 is stable up to 330 degrees 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. (C) 2008 Elsevier B.V. All rights reserved
