Abstract
Three new complexes, namely [Zn(mbix)(SO4)]·CH3OH (1), Cd(mbix)2(NO3)2 (2) and [Cd(mbix)2(H2O)2]·(NO3)2 (3), have been obtained by reactions of flexible bidentate ligand 1,3-bis(imidazol-1-ylmethyl)benzene (mbix) with corresponding zinc(II) and cadmium(II) salts. The structures of these complexes have been determined by the X-ray single crystal diffraction analysis. Complex 1 features a 2D wavy network with (4,4) topology. Complex 2 has a 2D grid network with left- and right-handed helical chains, while complex 3 exhibits twofold parallel interpenetration structure. The differences of three complexes demonstrate that the coordination geometry of metal ions and the ratio of reactants have a great impact on the structure of the supramolecular architectures. The luminescent properties of three complexes are also investigated.Three complexes have been constructed by different zinc(II) and cadmium(II) salts with the flexible mbix ligand. The results demonstrate that the metal ion and the ratio of reagents have an important effect on the structure of these complexes.
