Four new metal-organic frameworks of [Co4(biimb)3(DSBPDC)2(H2O)3]·9H2O (1), [Cd2(biimb)2(DSBPDC)(H2O)]·DMF·5.5H2O (2), [Cd2(biimb)(DSBPDC)(H2O)3]·H2O (3) and [Cd3Co(biimb)2(DSBPDC)2(H2O)6]·2H2O (4) (DMF = N,N-dimethylformamide) have been successfully synthesized by reactions of corresponding metal salts with imidazol-containing ligand 1,3-bis(1-imidazolyl)-5-(imidazol-1-ylmethyl)benzene (biimb) and 3,3′-disulfobiphenyl-4,4′-dicarboxylic acid (H4DSBPDC) under solvothermal conditions. The complexes were characterized by single crystal and powder X-ray diffractions, IR and thermogravimetric analyses. 1 is a 3D framework accompanied by antiferromagnetic interactions within the dinuclear Co(II) centers. 2 is a microporous 3D framework with different pore sizes and shapes along b and c axes, while 3 and 4 have the same 3D framework structure. Selectively gas adsorption and molecular sensing properties of the frameworks were investigated.
