氮杂大环钕配合物[Nd(L)(CH_3CN)(CF_3SO_3)_3]的合成和结构

Synthesis and Crystal Structure of Neodymium Complex of 1-Methyl-1, 4, 7, 10-tetraazacyclododecane

本文报道了三价钕与氮杂大环(简称L)配合物的合成和晶体结构.配合物组成为[Nd(L)-(CH_3CN)(CF_3SO_3)_3],晶体属于三斜晶系,空间群为PI,晶胞参数α=0.8738(2),b=1.2870(3),c=1.2900(3)nm;α=85.63(2),α=87.25(2),γ=78.30(2)°;最终偏差因子R=0.0370,R_w00385.配合物中钕为8配位,其配位多面体为扭曲的四方反棱柱体.

The complex [Nd(L)(CH_3CN)(CF_3SO_3)_3] has been synthesized. Where L-1-methyl-1, 4, 7, 10-tetraazacycldodecane. The crystal structure of the complex has been determined by a four-circle X-ray diffractometer to a final deviation factor R value of 0.0370 and R_w value of 0.0385 respectively. The crystal is triclinic system, space group PI with α=0.8738(2), b=1.2870(3), c=1.2900(3)nm, α=85.63(2), β=87.25(2), γ= 78.30(2)°, F=1.41571(60)nm^3, Z=2, D_c= 1.92g/cm^3. The neodymium ion ia eight-coordinated to forming a distorted square antiprism.
