Abstract

Five coordination polymers, namely, (Cd(mu(3)-5-nip)(mu-obix)](n) (1), [Co(mu(3)-5-nip)(mu-obix)](n) (2), [Zn(mu-5-nip)(mu-obix)](n) (3 and 4) and [Cd(mu-5-nip)(mu-bisobix)](n) (5) (5-nip: 5-nitroisophthalate, obix: 1,2-bis(imidazollylmethyl)benzene, bisobix: 1,2-bis(2-isopropylimidazol-lylmethyl)benzene) were hydrothermally synthesized and characterized by IR spectroscopy, elemental analysis, single crystal and powder X-ray diffraction and thermal analysis (TG/DTA). X-ray results showed that the complexes displayed structural diversity depending on metal ions and conformations of bis(imidazole) linkers. Complexes 1 and 2 were 1D structures and obix ligand displayed cis-conformation. Complexes 3 and 4 exhibited 2D and 3D structures with same components depending on obix conformation. In complex 5, 3D+3D -> 3D interpenetrated structure was obtained with dia topology when bisobix having sterically hindered groups on imidazole rings was used. Moreover, thermal, photoluminescence and optical properties of the complexes were also investigated.
