摘要
利用过渡金属镍盐、稀土盐与5-异烟酰胺吡啶基异酞酸水热合成了杂核化合物{[NiSm2(INAIP)4(H2O)4]·2H2O}n(1)(INAIP2-=异烟酰胺吡啶基异酞酸根),并对其进行了元素分析、IR及X-射线衍射法表征。晶体结构研究表明:配合物1属于三斜晶系,P-1空间群。配合物1是由配体异烟酰胺吡啶基异酞酸连接稀土钐离子形成二维层状结构,该二维层通过Ni-O和Ni-N键连接成三维非贯穿网络结构。配合物1脱水分子后具有稳定微孔结构,对二氧化碳具有一定吸附而对氮气无吸附作用。此外,配合物1还具有典型的稀土钐离子红色荧光性能。
A new heteronuclear coordination polymer {[NiSm2 （INAIP）4 （H 2 O）4 ]？2 H 2 O﹜n （1 ）,where H 2 INAIP = 5-（isonicotinamido）isophthalic acid,was synthesized and its crystal structure were determined by X-ray dif-fraction analysis.Complex 1 crystallizes in triclinic system with space group P-1 .In complex 1,each Sm （III）ion is eight-coordinated by seven carboxylate oxygen atoms from four different INAIP2-ligands and one from a coordinated water molecule with the distorted square antiprismatic geometry.Then the 2D Sm-carboxylate layer is linked by Ni-N and Ni-O interaction into 3D framework.Moreover,complex 1 shows selective adsorption behavior of CO2 over N2 ,and the luminescent property of 1 has also been investigated.
