| 摘要: 利用过渡金属锰盐与稀土盐水热合成了杂核化合物{[MnSm2(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=1.0188(5)nm,b=1.08386(6)nm,c=1.38721(8)nm,V=1.475(14)nm3,Z=1,Dc=1.802g·cm-3,μ=2.271mm-1,F(000)=793,Rint=0.0105,R1=0.0512,wR2=0.1319。配合物2属于单斜晶系,P21/c空间群。晶胞参数:a=1.34305(18)nm,b=1.3765(17)nm,c=1.62408(15)nm,V=2.7028(6)nm3,Z=4,Dc=1.861g·cm-3,μ=2.251mm-1,F(000)=1500,Rint=0.0514,R1=0.0322,wR2=0.0887。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 {[MnSm2(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=1.0188(5) nm, b=1.08386(6) nm, c=1.38721(8) nm, V=1.475(14) nm3, Z=1, Dc=1.802 g·cm-3, μ=2.271 mm-1, F(000)=793, Rint=0.0105, R1=0.0512, wR2=0.1319. Complex 2 is of monoclinic system, space group P21/c with a=1.34305(18) nm, b=1.3765(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)=1500, Rint=0.0514, R1=0.0322, wR2=0.0887. In complex 1, the 2D Sm-carboxylate layer is linked by Mn-Nand Mn-Ointeraction into complicated 3D framework. However, for complex 2, the central Sm(Ⅱ) 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 1 shows adsorption behavior of CO2 with almost no N2 uptake, and the luminescent property of complexes 1 and 2 has also been investigated. | |
