Synthesis and Three-Dimensional Hydrogen-Bonded Structure of A New Manganes Coordination Compound with Dinitronaphthalenedicarboxylate
【摘要】 将2,6-萘二甲酸(H2NDC)硝化制得1,5-二硝基萘-3,7-二甲酸(H2NNDC),再以H2NNDC为配体,辅以1,2-二吡啶基乙烯(bpe)共配,用液相扩散法合成新颖的锰(Ⅱ)配合物[Mn(bpe)(H2O)4](NNDC)獉2H2O.通过红外光谱、元素分析等方法对该配合物进行结构表征.结果表明,制得的配合物中,Mn2+与bpe、水分子形成单核配阳离子[Mn(bpe)(H2O)4]2+,NNDC2-为外界抗衡离子,bpe分子桥连Mn2+形成线性一维链[Mn(bpe)(H2O)4]n2n+,一维链在配位水分子、溶剂水分子及NNDC2-上未配位羧基氧所形成的多重氢键作用下,形成三维超分子氢键网络.
【Abstract】 2,6-naphthalic acid(H2 NDC)is nitrified to produce 1,5-dinitronaphthalene-3,7-dioctyl phthalate(H2 NNDC),which are synthesized into brand new Manganese(Ⅱ)complex 1 [Mn(bpe)(H2 O)4](NNDC)·2 H2 O with Liquid diffusion method by taking H2 NNDC as ligand and together with 1,2-Dipyridyl ethylene(bpe).The structure of 1 is characterized with methods of infrared and elemental analysis.The result shows that,Mn2+and bpe and water molecule in 1 formed mononuclear cation [Mn(bpe)(H2 O)4]2+,NNDC2-was external counterion,and the bridging of bpe molecule with Mn2+formed linear one-dimensional chain [Mn(bpe)(H2 O)4]2 n+n,which formed three dimensional supramolecular hydrogen bond network under the multiple hydrogen bonds interaction formed by coordination water molecules,solvent water molecules and NNDC2-uncoordinated carboxyl groups.
