用X-射线晶体结构衍射法测定了[C_5H_4C(CH_3)(C_3H_7)CH_2CH=CH_2]Gd(OH)Cl·2MgCl_2·4 THF的晶体结构。它属三斜晶系,空间群为P,a=1.2757(3),b=1.3571(3),c=1.3725(3)nm,α=69.22(3),β=84.91(3),γ=63.48(3)°,V=1.929(1)nm~3,Mr=862.75,D_X=1.423g/cm~3,μ=2.0832mm~(-1),F(000)=848,Z=2,R=0.096,wR=0.113(I≥3σ(I))。分子中Gd原子的配位数为8,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6,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。
The crystal structure of [C_5H_4C (CH_3) (C_3H_7) CH_2CH = CH_2] Gd (OH) Cl · 2MgCl_2 · 4 THF was determined by X-ray crystallography. It belongs to triclinic system with a space group of P = a = 1.2757 (3), b = 1.3571 (3), c = 1.3725 (3) nm, α = 69.22 (3), β = 84.91 63.48 (3) °, V = 1.929 (1) nm to 3, Mr = 862.75, DX = 1.423 g / cm 3, μ = 2.0832 mm -1, F (000) = 848 and Z = R = 0.096, wR = 0.113 (I ≧ 3σ (I)). The coordination number of the Gd atom in the molecule is 8, forming a severely distorted octahedral structure. The two Mg atoms coordinate in a similar manner, and their coordination numbers are both 6, forming two distorted octahedrons. The three octahedra are joined by three common planes.
