摘要：

Four new metal-organic frameworks of [Co-4(biimb)(3)(DSBPDC)(2)(H2O)(3)]center dot 9H(2)O (1), [Cd-2(biimb)(2)(DSBPDC)(H2O)]center dot DMF center dot 5.5H(2)O (2), [Cd-2(biimb)(DSBPDC)(H2O)(3)]center dot H2O (3) and [Cd3Co(biimb)(2)(DSBPDC)(2)(H2O)(6)]center dot 2H(2)O (4) (DMF=N,N-dimethylformamide) have been successfully synthesized by reactions of corresponding metal salts with imidazol-containing ligand 1,3-bis(1imidazoly1)-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. (C) 2016 Elsevier B.V. All rights reserved.
