摘要
本文报导了一种新化合物──含磷稠环－氧氮磷杂二苯并蒽烷吡啶盐的晶体结构和分子结构。其晶体学参数为：单斜晶系，空间群Ｐ２１／ｎ，ａ＝１．２１７８（７）ｎｍ。ｂ＝０．７４９５（５）ｎｍ，ｃ＝１．５６２７（２）ｎｍ，β＝１０１．４４（９）°，ｚ＝４，最终偏离因子Ｒ＝０．０７０和Ｒｗ＝０．０５３。该化合物由吡啶盐正离子和氧氮磷杂稠环负离子组成，靠氢键力维系在一起。本文比较了几个相关化合物的晶体结构，表明它们构型的差异与吡啶成盐有关。
The crystal structure of the title compound 6,13-dithione-5,12-dioxa-6a,7,13a,14-tetraza-6,13- diphosphadibenzo(a,h) anthracece pyridinium dihydrate has been determined.The crystal data are as follows: monoclinic,space group P21/n,a=1.2178(7)nm,b=0.7495(5)nm,c=1.5627(2)nm,β=101.44(9)°,z=4,the final discrepancy factors are R=0.070 and Rw=0.053.The title compound consists of a pyridinium cation and a condensed phosphorous ring anion and hold together by hydrogen bondings.Compared with the crystal structures of some analogues,the crystal structure of these compound concerned with the pyritine anion.
