Syntheses and Crystal Structures of One-dimensional Ni(Ⅱ) Complexes with 5-Tert-butyl Isophthalic Acid

摘要

Two new Ni(Ⅱ) coordination polymers,{[Ni(tbip)(bipy)(H2O)]·0.5H2O}n 1 and [Ni(tbip)(phen)(H2O)]n 2(H2tbip=5-tert-butyl isophthalic acid,bipy=2,2′-bipyridine,phen=1,10-phenanthroline),have been synthesized under hydrothermal conditions and characterized by elemental analysis,X-ray diffraction,and IR spectroscopy.In the two polymers,H2tbip acts as a tridentate ligand.Compound 1 has a tbip bridged 1-D linear chain which is extended by hydrogen bonds into a 1-D double chain,while compound 2 exhibits a 1-D zig-zag chain.
