Three new complexes, [Zn(dtb)(4,4'-bipy)]·5H2O (1), [Zn(dtb)(bpp)]·H2O (2) and [Zn(dtb)(phen)2]·CH3CH2OH·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.

0 Introduction The realm of crystal engineering has provided a sound junction between aesthetics of crystalline architectures[1-2]and their potential functions[3-4],of which the ultimate destination is to successfully
A new flexible 3D porous metal-organic framework （MOF） with 1D open nanotube, [Co2（/zs-CTAl）（dpe）（H20）2]n-6n（H20） （1） （CTA = cyclohexane-1,2,4,5-tetracarboxylic acid, dpe = 1,2-di（4-pyridyl） ethylene） has been prepared and structurally character- ized. Meanwhile, each 1D nanotubes filled with 1D water chain with dimension of 13.711 ~ 12.275/~2. Compound 1 represents a new example that collapse/deform upon dehydration/hydration and shows adsorb 1-120 selectively over organic solvents.
