CCDC[2]: 2353118. | | Q: Structure 230530b_0m_a (CCDC 2353117): C56 H68 Er2 N6 S2 Si4 The absorption coefficient is given as 2.734. Absorption correction must be carried out and reported correctly. Tmax is reported as 0.7456 and Tmin is given as 0.3833. The absorption correction type is reported as 'none'. Additional Info: The crystal size is given as 0.21 x 0.2 x 0.19 mm^3.) A: This problem has been solved in the revised CIF and updated in CCDC. | 问:Structure 230530b_0m_a (CCDC 2353117): C56 H68 Er2 N6 S2 Si4 吸收系数为2.734。必须执行并正确报道吸收校正。Tmax报道为0.7456,Tmin给定为0.3833。吸收校正类型报道为“none”。附加信息:晶体尺寸给定为0.21 × 0.2 × 0.19 mm3。 答:该问题已解决,并在CCDC中更新了修正的CIF。 |
查看CIF[3]文件如图1所示,吸收校正相关信息非常全面,唯独“_exptl_absorpt_correction_type”条目(参阅推文“CIF核心词典-EXPTL”)的值为“none”,这属于最终检查没到位造成的。 ▲图1 CCDC 2353118投稿时CIF 根据实际情况将其修正为正确值(本例为“multi-scan”)即可,如图2所示。 ▲图2 CCDC 2353118发表时CIF 相关视频: 晶体数据审稿意见-条目信息错误(吸收校正):https://www.bilibili.com/video/BV14n4y1f7ja | [2] (a) Allen, F.
