Three new metal-organic frameworks [Cd(L)(obba)]·H)2O(1),[Co(L)(obba)]·MeCN(2) and [Cd_2(L)_2(ip)_2]·6H_2O·DMF(3)(H_2obba = 4,4?-oxybisbenzoic acid,H2 ip = m-phthalic acid) have been successfully synthesized based on the controllable self-assembly of 9-ethyl-3,6-diimidazolyl-carbazole(L),varied carboxylates and different metal ions under solvothermal conditions,which were characterized by single-crystal X-ray diffraction,elemental analysis,IR spectroscopy and thermogravimetry. Furthermore,luminescence and magnetic susceptibility of compound 2 are also investigated in detail. Single-crystal X-ray diffraction and topology analysis reveal that complexes 1~3 exhibit similar two-dimensional(2D) networks.
