Hydrogen-bonding Directed Three-dimensional Supramolecular Structure in Catena-((μ2-4,4'-bipyridine)-tetraaqua-cobalt (Ⅱ) bis (2-methylbenzimidazolium-1,3-diacetate) dehydrate) :Synthesis and Crystal Structural Characterization
摘要
Abstract
The title compound,{ [Co (4,4'-bipy) (H2O)4] (pda)2 (H2O)2 }n,was obtained by the hydrothermal reaction of cobalt acetate with 3-carboxymethyl-1,3-(2-methylbenzimidazolium)-1-acetate (Hpda) and 4,4'-bipyridine (4,4'-bipy).X-ray single crystal diffraction shows that the asymmetric unit of the title compound contains half a Co2+ ion,half a 4,4'-bipy molecule,one counter anion pda-,two coordinated water molecules and one lattice water molecule.Co2+ ions are bridged by 4,4'-bipy molecules resulting in a one-dimensional coordination chain,{[Co (4,4'-bipy) (H2O)4]2+ }n,in which Co2+ center is six-coordinated by two nitrogen atoms from different 4,4'-bipy molecules and four oxygen atoms from coordinated water molecules.In the solid state,two-dimensional undulating layers are constructed through hydrogen bonds between pda-anions,coordinated water and crystallization water molecules,while neighboring hydrogen-bonding layers are further pillared by 4,4'-bipy into a three-dimensional supramolecular structure which contains one-dimensional channels.关键词
