摘要
利用不同过渡金属盐在溶剂热中合成了2个杂核化合物{[CuEu2(INAIP)3(HCOO)(H2O)3]·3H2O}n(1)和{[NiEu2(INAIP)4(H2O)4]·4H2O}n(2)(INAIP=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和2都属于三斜晶系,P1空间群。晶胞参数:配合物1 a=1.088 7(3)nm,b=1.515 8(4)nm,c=1.564 4(2)nm,V=2.333 2(10)nm3,Z=2,Dc=1.955 g·cm-3,μ=3.203 mm-1,F(000)=1352,Rint=0.027,R1=0.0505,wR2=0.1309。配合物2 a=1.013 4(3)nm,b=1.083 6(6)nm,c=1.374 1(2)nm,V=1.453 0(9)nm3,Z=1,Dc=1.878 g·cm-3,μ=2.554 mm-1,F(000)=818,Rint=0.045 8,R1=0.034 1,wR2=0.086 9。配合物1是由配体异烟酰胺吡啶基异酞酸连接而成的三维二重贯穿sqc27拓扑结构,而配合物2是由配体异烟酰胺吡啶基异酞酸连接稀土铕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和2具有典型的稀土铕离子红色荧光和高的热稳定性。
Two 3d-4fheteronuclear coordination polymers {[CuEu2 (INAIP)3 (HCOO)(H2O)3]·3H2O}n (1) {[NiEu2 (INAIP)4(H2O)4]· 4H2O}n(2) were obtained by solvothermal assembly of CuCl/NiSO4·7H2O and Eu(NO3)3· 6H2O with the H2INAIP (5-(isonicotinamido)isophthalic acid) ligand.Both complex 1 and 2 crystallize in triclinic,space group P1.For 1:a=1.088 7(3) nm,b=1.515 8 (4) nm,c=1.564 4 (2) nm,V=2.333 2 (10) nm3,Z=2,Dc=1.955 g·cm-3,μ=3.203 mm-1,F(000)=1 352,Rint=0.027,R1=0.050 5,wR2=0.130 9.a=l.013 4(3) nm,b=1.083 6 (6) nm,c=1.374 1 (2) nm,V=1.453 0 (9) nm3,Z=1,Dc=1.878 g·cm-3,μ=2.554 mm-1,F(000)=818,Rint=0.045 8,R1=0.034 1,wR2=0.086 9 for 2.Single-crystal X-ray diffraction analysis revealed that each INAIP2-ligand uses its two carboxyl groups to connect two or three Eu(llⅢ) ions into 2D lanthanide bi-layer structure.Then the 2D layers are further connected by pyridyl groups to give a three-dimensional two-fold interpenetrated pillared-layer structure in 1 with sqc27 topology.While in complex 2,the Ni(Ⅱ) bonds to the pyridyl group (N) and carboxylate group (O) linking the 2D lanthanide layer into a 3D framework.In addition,the luminescent properties of complexes 1 and 2 have been investigated,which showed the obviously red photoluminescence in them.CCDC:943863,1; 966618,2.
