【摘要】 利用过渡金属锰盐与稀土盐水热合成了杂核化合物{[Mn Sm2(INAIP)4(H2O)4]·2H2O}n(1)和同核{[Sm(INAIP)(HINAIP)]·2H2O}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属于三斜晶系,P1空间群。晶胞参数:a=1.018 8(5)nm,b=1.083 86(6)nm,c=1.387 21(8)nm,V=1.475(14)nm3,Z=1,Dc=1.802 g·cm-3,μ=2.271 mm-1,F(000)=793,Rint=0.010 5,R1=0.051 2,w R2=0.131 9。配合物2属于单斜晶系,P21/c空间群。晶胞参数:a=1.343 05(18)nm,b=1.376 5(17)nm,c=1.62408(15)nm,V=2.7028(6)nm3,Z=4,Dc=1.861 g·cm-3,μ=2.251 mm-1,F(000)=1 500,Rint=0.051 4,R1=0.032 2,w R2=0.088 7。配合物1是由配体INAIP连接稀土钐离子形成二维层状结构,该二维层通过Mn-O和Mn-N键连接成三维非贯穿网络结构。而配合物2是由配体INAIP连接稀土钐离子形成二维双层状结构,该二维层通过氢键连接成三维网络结构。配合物1失去水分子后具有稳定微孔结构,对二氧化碳具有一定的吸附,而对氮气没有吸附作用。此外,配合物1和2具有典型的稀土钐离子红色荧光性能。

【Abstract】 Two heteronuclear/homonuclear coordination polymers {[Mn Sm2(INAIP)4(H2O)4]·2H2O}n(1) and {[Sm(INAIP)(HINAIP)]·2H2O}n(2), where H2INAIP=5-(isonicotinamido)isophthalic acid, were synthesized in a pot and their crystal structures were determined by X-ray diffraction analysis. Complex 1 crystallizes in the triclinic system, space group P1 with a=1.018 8(5) nm, b=1.083 86(6) nm, c=1.387 21(8) nm, V=1.475(14) nm3, Z=1, Dc=1.802 g·cm-3, μ=2.271 mm-1, F(000)=793, Rint=0.010 5, R1=0.051 2, w R2=0.131 9. Complex 2 is of monoclinic system, space group P21/c with a=1.343 05(18) nm, b=1.376 5(17) nm, c=1.624 08(15) nm, V=2.702 8(6) nm3, Z=4, Dc=1.861 g·cm-3, μ=2.251 mm-1, F(000)=1 500, Rint=0.051 4, R1=0.032 2, w R2=0.088 7. In complex 1, the 2D Sm-carboxylate layer is linked by Mn-N and Mn-O interaction into complicated 3D framework. However, for complex 2, the central Sm(Ⅲ) atom is eight-coordinated by eight carboxylate oxygen atoms. The molecules are connected to form a 2D bilayer structure bridged by 5-(isonicotinamido)isophthalic acid. Furthermore, complex 1shows adsorption behavior of CO2 with almost no N2 uptake,and the luminescent property of complexes 1 and 2has also been investigated. CCDC: 1045729, 1; 1045730, 2.
