Abstract

Three new complexes, [Zn(dtb)(4,4′-bipy)]·5H2O (1), [Zn(dtb)(bpp)]·H2O (2) and [Zn(dtb)(phen)2]·CH3-CH2OH·H2O (3) (dtb = 5,5′-dithiobis(2-nitrobenzoic acid), 4,4′-bipy = 4,4′-bipyridine, bpp = 1,3-bi(4-pyridyl) propane, phen = 1,10-phenanthroline), have been constructed by dtb ligand and zinc salt in the presence of different assistant N-containing ligands under hydrothermal conditions. The structures of the complexes were established by single-crystal X-ray diffraction analysis. Although compounds 1 and 2 are both 2D networks, the cavities’ forms and pitch of helix are different. The structure of compound 3 shows a 1D helical chain, and is extended by the supermolecule interactions into a 2D framework. These neutral polymeric complexes exhibit structural and dimensional diversity due to the different coordination modes of the flexible dtb ligand and the effect of assistant ligands.
