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.
