[C5H4C(CH3)(C3H7)CH2CH=CH2]NdMg2(μ3-OH)(μ3-Cl)(μ2-Cl)3(THF)4Cl的合成和晶体结构分析
SYNTHESIS AND CRYSTAL STRUCTURE ANALYSIS OF [C5H4C(CH3)(C3H7)CH2CH=CH2]NdMg2(μ3-OH)(μ3-Cl)(μ2-Cl)3(THF)4Cl
【摘要】 用X-射线衍射法测定了[C5H4C(CH3)(C3H7)CH2CH= CH2]NdMg2(μ3-OH)(μ3-Cl)(μ2-Cl)3(THF)4Cl的晶体结构。它属三斜晶系,空间群为P1- ,a= 12.698(3), b= 13.616(3), c= 13.712(3), α= 68.91(3), β= 84.34(3), γ= 63.07(3)°, V= 1966(1)3, Mr= 849.74, Dx= 1.412 g·cm - 3, μ= 1.7297 m m - 1, F(000)= 840, Z= 2, R= 0.073, w R= 0.086(I≥3σ(I))。分子中Nd(Ⅲ)原子的配位数为八,形成一个严重扭曲的八面体结构。两个Mg 原子的配位情况相似,它们的配位数都是六,构成两个扭曲的八面体。这三个八面体通过三个共用平面联接
【Abstract】 The crystallographic data are as follows: space group P1-, a=12.698(2), b=13.616(3), c=13.712(3), α=68.91(3), β=84.34(3), γ=63.07(3)°, V=1966(1) 3, M r=849.74, D x=1.412 g·cm -3 , μ= 1.7297 mm -1 , F (000)=840, Z=2, R =0.073, w R=0.086(I≥3σ(I)). In this molecule the coodination number of Nd(Ⅲ) atom is 8 and the coordination geometry of Nd(Ⅲ) is a seriously distorted octahedron. The coordinations of Mg(1) and Mg(2) are similar, their coordination numbers are all 6 and their coordination geometries are all distorted octahedra. The three octahedra are linked up by three coplanes.
