晶体数据审稿意见-无序处理(不要偷懒) 案例来源:CCDC[1] 2347593‒2347594. Chem. Sci. 2024, 15, 11928‒11936. DOI[2]: 10.1039/d4sc02550d. 审稿意见: 1. The crystal structure of NPU-6 should be refined taking intoaccount the inversion twin the authors postulate is present. 2. The authors have not modelled the disorder of the1,4-benzenedicarboxylate but instead applied a SIMU restraint to the entirestructure. This is a rather lazy way of addressing this issue (and masks thepresence of disorder), when modelling the disorder would give a more accuraterepresentation of the structure. 大意: 1. 考虑到作者提出的倒反孪晶,NPU-6的晶体结构应该得到改进。 2. 作者没有对1,4-苯二甲酸酯的无序进行建模,而是对整个结构应用了SIMU限制。这是一种相当懒惰的方法来解决这个问题(并掩盖了无序的存在),因为对无序进行建模可以更准确地表示结构。 两个结构中均采用了SIMU和ISOR限制,未进行无序建模,随后对这两个结构中的无序进行适当建模,并精简限制指令,也进行了适当的原子编号,处理前后对比如图1‒4所示(由Olex2[3]呈现)。 ▲图1 CCDC 2347593投稿时状态 ▲图2 CCDC 2347593发表时状态 ▲图3 CCDC 2347594投稿时状态 ▲图4 CCDC 2347594发表时状态 对于结构中存在的无序,正如审稿人所说,不能偷懒用限制指令掩盖了事,无序建模能更准确表达结构。 视频操作演示请参阅: 晶体数据审稿意见-无序处理(不要偷懒):https://www.bilibili.com/video/BV1ACDCYcEfw 如需论文PDF和已发表CIF[4]文件,请从以下链接下载: 提取码: i8va 参考文献 [1] (a) Allen, F.
