Hydrothermal reactions of CdCl2·2.5H2O with 4,4'-bis(1-imidazolyl)bibenzene (bimb) and 1,3-benzenedicarboxylate (1,3-H 2BDC), 5-methyl-1,3-benzenedicarboxylate (5-Me-1,3-H2BDC), 5-amino-1,3-benzenedicarboxylate (5-NH2-1,3-H2BDC), 5-hydroxy-1,3-benzenedicarboxylate (5-HO-1,3-H2BDC), 5-nitro-1,3-benzenedicarboxylate (5-NO2-H21,3-BDC), or 5-sulfo-1,3-benzenedicarboxylate (5-HSO3-1,3-H2BDC) resulted in the formation of six Cd(ii) coordination polymers, [Cd(5-R-1,3-BDC)(bimb)]n (R = H (1), R = Me (2), R = NH2 (3), R = OH (4)), {[Cd2(H2O)(5-NO2-1,3-BDC) 2(bimb)]·2H2O}n (5) and [Cd(5-SO 3-1,3-HBDC)(bimb)]n (6). Compounds 1-6 were characterized by elemental analysis, IR, powder X-ray diffraction and single-crystal X-ray diffraction. 1-4 exhibit similar 3D frameworks in which 2D [Cd 4(5-R-1,3-BDC)4]n (R = H, Me, NH2 and OH) layers are interlinked by bimb ligands. 5 has a two-fold interpenetrating 3D framework in which 1D [Cd2(5-NO 2-1,3-BDC)2]n chains are interconnected by bimb ligands. 6 shows a 3D (3,5)-connected framework in which 2D [Cd 2(5-SO3-1,3-HBDC)2]n networks are bridged by bimb ligands. The Schlaefli symbols for these six 3D nets are (4·62)(4·66·83) (1-4), (42·6)(42·6·102·12) (5) and (4·6·8)(4·65·8 3·10) (6). The solid state photoluminescent properties of 1-6 were also investigated.
