摘　　要：以1,2-苯二甲酸(1,2-H2bdc)和N,N′-二(3-吡啶基)-1,3-甲酰胺-5-羟基苯(L)为混合配体,利用中温水热合成方法获得了一维配位聚合物[Ni(L)(bdc)(H2O)2]·3H2O,并通过元素分析、IR和单晶X-射线衍射技术确定了该配位聚合物的晶体结构.单晶结构分析表明,配位聚合物中的NiⅡ与1个bdc阴离子以及2个配位水分子形成单金属-有机结构单元[Ni(bdc)(H2O)2].相邻的上述结构单元通过μ2配位模式的L配体拓展成一维波浪形配位聚合物,并最终通过氢键作用拓展成三维超分子框架.另外,研究了该配位聚合物的相纯度、荧光性质以及光催化性质.A one-dimensional(1 D)coordination polymer of[Ni(L)(bdc)(H2O)2]·3H2 O has been hydrothermally synthesized from 1,2-benzenedicarboxylic acid(H2 bdc)and N,N′-bis(pyridin-3-yl)-5-hydroxybenzene-1,3-dicarboxamide(L),and structurally characterized by elementary analysis,IR and single crystal X-ray diffraction analysis.The single-crystal structure analysis indicates that the NiⅡcation combines with one bdc anion and two coordinated water molecules to form single metal-organic subunit[Ni(bdc)(H2 O)2].The adjacent subunits are linked byμ2-L to form a 1 Dwave-like coordination polymer,which finally shows 3 Dsupramolecular structure extended by hydrogen-bonding interactions.Moreover,the phase purity,photoluminescent property and photocatalytic activity of the title complex were investigated.
