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(H 2 O)4]?2 H 2 O}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 ...
