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 heteronuclear compounds {[CuEu2 (INAIP) 3 (HCOO) (H2O) 3] · 3H2O} n (1) and {[NiEu2 (INAIP) 4 (H2O) 4 were synthesized by solvothermal method using different transition metal salts ] · 4H2O} n (2) (INAIP = isonicotinamide pyridyl isophthalate), and its elemental analysis, IR and X-ray diffraction characterization. Crystal structure studies show that both complexes 1 and 2 belong to triclinic system, space group P1. The parameters of the unit cell were as follows: 1 a = 1.088 7 (3) nm, b = 1.515 8 (4) nm and c = 1.564 4 (2) nm, V = 2.333 2 (10) nm3, Z = 2 and Dc = 1.955 g · cm-3, μ = 3.203 mm-1, F (000) = 1352, Rint = 0.027, R1 = 0.0505, wR2 = 0.1309. The complex 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 and 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. Complex 1 is a three-dimensional double-through sqc27 topology formed by the attachment of isonicotinamide pyridyl isophthalic acid, while complex 2 is formed by coupling the ligand isonicotinamide pyridyl isophthalic acid to rare earth europium ions to form a two-dimensional Layered structure that is connected to a three-dimensional non-through network structure by Ni-O and Ni-N bonds. Complex 1 and 2 have the typical rare earth europium ion red fluorescence and high thermal stability.
