Abstract
Two new metal–organic coordination complexes, {[Cd8(tdc)8(bbi)8(H2O)8]·4DMF]}n (1) and {[Cd(cbba)2(m-bix)2]}n (2) (H2tdc = 2,5-thiophenedicarboxylic acid, bbi = 1,1′-(1,4-butanediyl)bis (imidazole), Hcbba = 2-(4-chlorobenzoyl)benzoic acid, m-bix = 1,3-bis((1H-imidazolyl)-methyl) benzene) were synthesized under hydrothermal conditions and characterized by techniques of single-crystal X-ray diffraction analysis, elemental analysis, powder X-ray diffraction and thermogravimetric analysis (TGA). Single-crystal structure analyses reveal that complex 1 displays a 3D 4-connected threefold interpenetrating framework with the point symbol of {42·84}. Complex 2 shows a 3D supramolecular architecture via intermolecular hydrogen bonds and intermolecular π⋯π stacking interactions. Furthermore, the luminescence of the two complexes was also studied.
