| 摘 要： | 无水三氯化稀土LnCl3与1倍量的胺基桥联双芳氧基钠LNa2L=Me2NCH2CH2N{CH2-(2-O-C6H2-But-3-Me-5)}2]在四氢呋喃中室温下反应生成胺基桥联双芳氧基稀土金属氯化物LLnCl(THF)(Ln=Yb(1),Ln=Er(2)).这些配合物都经过了元素分析和红外光谱表征,并测定了配合物1的晶体结构.配合物1·C7H8(C39H58ClN2O3Yb,Mr=811.36)属于单斜晶系,P21/c空间群,a=9.361 5(8),b=14.287(1),c=29.493(3)(A),β=98.516(2)°,V=3 901.1(6)(A)3,Z=4,Dc=1.381 g.cm-3,λ(Mo Kα)=0710 70 (A),μ=2.502 mm-1,F(000)=1 668,R=0.0267,wR=0.061 6.中心金属与来自胺基桥联双芳氧基配体上的2个氧原子和2个氮原子以及1个氯原子和1个来自四氢呋喃的氧原子配位,形成1个六配位的扭曲的八面体几何构型.

| Abstract: | Reaction of anhydrous lanthanide trichlorides with 1 equiv of sodium amine bis(phenolate)LNa2 L=Me2NCH2CH2N {CH2-(2-O-C6H2-But-3-Me-5)}2] in THF at room temperature gave the amine bis(phenolate) lanthanide chlorides LLnCl(THF) (Ln = Yb (1), Ln = Er (2)). These complexes were well characterized by elemental analyses, IR spectra and, in the case of complex 1, single crystal X-ray P21/c with a=0.936 15(8) nm, b=1.428 7(1) nm, c=2.949 3(3) nm, β=98.516(2)°, V=3.901 1(6) nm3, Z=for 6 723 observed reflections with I ＞ 2σ(l). The central metal atom is coordinated six fold by two oxygen atoms and two nitrogen atoms from the amine bis(phenolate) ligand, one THF molecule and one chlorine atom in a distorted octahedron. |
