摘要： 用X射线衍射方法测定了两个1,3,2-氧氮磷杂环戊烷衍生物的晶体结构:2-二乙氨基-3-(4'-甲基苯甲酰基)-2-硫代-1,3,2-氧氮磷杂环戊烷,C14H21N2O2PS(1),空间群为Pbco,α=0.9057(5)nm,b=1.3974(6)nm,c=2.5130(7)nm,Z=8,R=0.051;2-二乙氨基-3-(2',4'-二氯苯甲酰基)-2-硫代-1,3,2-氧氮磷杂环戊烷,C13H17N2O2PSCl2(2),空间群P21/c,α=0.7375(1)nm,b=1.4370(3)nm,c=1.6015(7)nm,β=93.70(2)°,Z=4,R=0.054。结构均由直接法解出。两个化合物中氧氮磷杂五元环均为半椅式构象。其中P—N键长环内分别为0.1712(2)nm和0.1723(0)nn;环外为0.1620(3)nm和0.1620(0)nm,由于成环作用所致环内P—N键长大于环外的。
