Syntheses, Structures, Luminescence and Magnetic Properties of Three New Metal-organic Frameworks Based on Rigid Carbazole Ligand

Three new metal-organic frameworks [Cd(L)(obba)].H2O (1), [Co(L)(obba)] . MeCN (2) and [Cd-2(L)(2)(ip)(2)].6H(2)O.DMF (3) (H(2)obba = 4,4'-oxybisbenzoic acid, H(2)ip = m-phthalic acid) have been successfully synthesized based on the controllable self-assembly of 9-ethyl-3,6diimidazolyl- 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 similar to 3 exhibit similar two-dimensional (2D) networks.
