摘要
利用水热合成制备了一个新的吡啶基多羧酸钇配合物YL(HL).2H2O(1)(H2L=5-((吡啶基-3-亚甲基)氨基)间苯二甲酸)。利用元素分析及X-射线单晶衍射对其进行了表征。结构分析结果表明标题化合物1属于三斜晶系,P1空间群,晶胞参数为a=1.015 35(11)nm,b=1.083 33(12)nm,c=1.287 40(14)nm,α=70.9430(10)°,β=127.689(3)°,γ=84.0680(10)°,晶胞体积V=1.317 0(2)nm3,Z=2,Dc=1.680 g.cm-3,F(000)=680,μ=2.284 cm-1,R=0.056 2,wR=0.1600。在化合物1中,每个Y的配位环境为八配位的反四棱柱配位构型。该配合物的二维结构是少见的(42.6)(42.67.8)层状拓扑。我们对配合物1的粉末衍射数据和热重分析也进行的讨论。
By using hydrothermal method, the reaction with yttrium nitrate led to the formation of a novel yttrium 5-((pyridine-3-ylmethyl)amino)isophthalic acid (H2L) complex, namely, YL(HL)· 2H2O (1), with interesting two-dimensional (2D) topology. The title complex was characterized by elemental analysis and IR spectroscopy and its structure was determined by single crystal X-ray structural analysis. The result of structural analysis shows that the 1 crystallizes in triclinic, space group P1 with α=1.015 35(11) nm, b=1.083 33(12) nm, c=1.287 40(14) nm, α=70.9430(10)°, β=127.689(3)°, y=84.0680(10)°, V=1.317 0(2) nm3, Z=2, Dc=1.680 g·cm^-3, F(000)=680,μ=2.284 cm-1, R=0.056 2, wR=0.160 0. The Y(Ⅲ)atoms was eight-coordinated with carboxylate O atoms in square- antiprismatic geometry. In complex 1, the 2D layer comprised of μ2/μ3ligands and 5-connected Y(Ⅲ) centers is rare example of 2-nodal net of (42.6)(42.67.8) topology. The XPRD and TGA analysis were also investigated.
