【摘要】 HO-4,6-tBu2-C6H2-2-CH2Cl与Yb[N(TMS)2]3按照摩尔比为2:1在THF中反应生成镱和锂的双金属配合物LiYb[(O-4,6-di-tBu2-C6H2)2(CH2)]Cl2[THF]4,配合物经过元素分析和晶体结构测试表征,结果表明配合物是亚甲基桥连双酚镱和锂的双金属配合物。配合物为三斜晶系a=13.691(2)?,b=14.852(2)?,c=15.571(3)?,?=110.739(3)°,β=97.198(2)°,?=97.622(2),V=2883.7(8)?3,Mr=1100.12,Z=2,Dc=1.267g/cm3,μ(MoKα)=1.758mm-1 and F(000)=1148.配合物中,中心金属(Yb)和来自桥连双酚[(O-4,6-di-tBu2-C6H2)2(CH2)]两个氧负离子O(1)、O(2)和两个氯原子Cl(1)、Cl(2)以及来自THF的两个氧原子O(3)、O(4)形成扭曲的八面体的几何构型。锂离子和两个氯原子Cl(1)、Cl(2)以及来自THF的两个氧原子配位形成扭曲的四面体的几何构型。更多还原

【Abstract】 The title complex LiYb[(O-4,6-di-tBu2-C6H2)2(CH2)]Cl2[THF]4 has been synthesized by the reaction of HO-4,6-tBu2-C6H2-2-CH2Cl with Yb[N(TMS)2]3 in a 1:3 molar ratio in THF, and characterized by elemental analysis and single-crystal X-ray diffraction analysis. It crystallizes in Triclinic with a =13.691(2) , b =14.852(2) , c = 15.571(3), = 110.739(3)°,β = 97.198(2)°, = 97.622(2),V = 2883.7(8) 3, Mr =1100.12, Z = 2, Dc = 1.267g/cm3, μ(MoKα) =1.758mm-1 and F(000) = 1148。The central metal(Yb) is coordinated to two O anions,two Cl(1,2) atoms and two O atoms from THF,adopting a distorted octahedral geometry and the metal Lithium is coordinated to two Cl(1,2) atoms and two O atoms from THF to form a distorted tetrahedron.更多还原
