[求助] 编辑给的回信是这样,是不是就发不了单晶了?还有什么补救办法吗

I have reviewed your structure report and before going into any detail I would like to ask whether there is a possibility to find a better crystal? You report only 1862 observed reflections but 268 refined parameters. Since the data/parameter ratio for a properly refined structure should approximately be 10 your data set contains not enough data to refine such a number of parameters. In additon, there are no negative intensities in the data set. Have they been merged? Probably because there were too much of them due to a either very small or unsufficiently diffracting crystal?

If I additionally take into account that for a refinement with a low data/parameter ratio R values are lower due to statistic effects, your structure from my point of view does not meet the standards of Acta E.

确定要重新收集,找个好点的参数,或者跟收集的老师说,曝光时间放长一些试试,不过根据编辑的意思还是找个好点的晶体重新收集。

就是说你晶体的可观测衍射点数量偏少。那个比率一般要10以上吧。审稿人建议选一个更好的晶体重新收录数据。

审稿人选的太严了,我再重修一下数据试试,谢谢
