A New One-dimensional Zigzag Chain [Zn(1,5-NDC)(2,2′-bipy)]_n Obtained from Hydrothermal Reaction

1 INTRODUCTION The coordination polymers have attracted much attention in recent years owning to their fascinating molecular structures and potential applications as catalysts, luminescent materials and magnetic materials1～6]. Consequently, numerous new com- pounds have been produced mostly by using appro- priate organic ligands, especially bridging ligands containing multi-dentate oxygen, nitrogen, or sulfur donors to coordinate with the transition metal centers7～10]. Among them, 1,4…

A New One-dimensional Zigzag Chain [Zn(1,5-NDC)(2,2′-bipy)]_n Obtained from Hydrothermal Reaction

The title compound, Zn(NDC)(2,2′-bipy)]n (NDC = 1,5-naphthalenedicarboxylate, 2,2′- bipy = 2,2′-bipyridine), has been synthesized by a hydrothermal reaction and characterized by single-crystal X-ray diffraction analysis. It crystallizes in monoclinic, space group C2/c with a = 19.967(4), b = 17.158(3), c = 14.276(3) ', β = 129.623(5)°, V = 3767.4(12) '3, Z = 8, C22H14N2O4Zn, Mr = 435.72, Dc = 1.536 g/cm3, F(000) = 1776, μ(MoKa) = 1.336 mm-1, the final R = 0.0777 and wR = 0.2447 for 2032 observed reflections (I > 2σ(I)). The Zn(II) ion is six-coordinated by two nitrogen and four oxygen atoms in a distorted octahedral environment. NDC ligand has a bis(bridging bidentate) coordination mode in the compound. The zinc atoms are linked by carboxylate groups of NDC ligand in bridging mode into a one-dimensional zigzag chain.
