关于空间群判断失误的扎记 V.晶系不变情况下的非心群修正

我们发表胡盛志教授的“札记” ,一是想提醒晶体结构工作者们在晶体结构测定过程对空间群的指定应十分小心 ,尽量减少差错 ;同时也想借此透露一些国外同行在纠正空间群测定差错这一方面的工作 ,引起国内同行关注和响应。至于胡教授“札记”的论证方法的客观性 ,论据的充分性等 ,因纯系个人的见解 ,十分欢迎有不同意见者结合实例来稿进行讨论。

On the Incorrect Assignment of Space Groups V. Revisions of Non-centrosymmetric to Centrosymmetric Structure without Changing Crystal System

Twelve examples of crystal structures, which were originally described as non-centrosymmetric, are properly~ described as centrosymmetric. Of which two triclinic and eight monoclinic cases are simply revised by insertion~ of a missing centre of symmetry, and also one example each changes from orthorhombic Pbn2 1 to Pnma and Pma2 to Pmna.
