摘要：
The complex Pr (NO3)3 (Me2-16-C-5) (Me2-16-C-5 = 3, 3-dimethyl-1,5,8,11,14-pentaoxacyclohexadecane) crystallizes in the hexagonal space group P65with a = b = 13. 145(2), c=25. 611(5) A ; Z = 6; V = 3832(1)A3; Dc = 1. 53gcm-3; F (000) = 1776;μ= 19. 7cm-1 (MoKa). The final refinement converged with R = 0. 049 and Rw = 0. 051 for 2005 observed reflections. The Pr(Ⅲ) ion is 11-coordinated to three bidentate nitrate groups and five oxygen atoms of a crown ether. The average Pr -O(crown) and Pr -O(NO3-) bond lengths are 2. 68 and 2. 57A , respectively.
