[求助] 审稿意见关于晶体数据的问题,跪求高手!!!已有1人参与

Structure 1.
The short intermolecular contact O(1)...O(4) (x,y-1,z) 2.56 Ang suggests a hydrogen bond, yet the hydrogens on both these atoms point in different directions, into voids where there are no suitable H-bond acceptors.
======
Structure 2
The bond O(9)-H(9B) points almost directly towards Sr(1), resulting in an impossibly short contact H...Sr of 1.88 Ang.
======
Structure 3
The molecule overlaps with its translational equivalents, resulting in impossibly short contacts O(17)...O(10)(x-1,y-1,z) 1.18 Ang and O(19)...O(14)(x+1,y,z) 1.31 Ang. Furthermore, most atoms fit into space group P-1, with the inversion centre (origin) at x=0.1554, y=0.1270, z=0.0051. Please investigate.

先升空间群再重新加氢。...

化合物1和2的结构没问题,怎么加氢才行呢 Without Acceptor O1 - H1C ... Please Check 怎么加氢?

1,2表示加氢可能有问题。
3表示应该是P-1空间群,仔细检查下你的结构吧。

1:PLAT420_ALERT_2_B D-H Without Acceptor O1 - H1C ... Please Check
    PLAT420_ALERT_2_B D-H Without Acceptor O4 - H4B ... Please Check
2:PLAT417_ALERT_2_B Short Inter D-H..H-D H5A .. H10A .. 1.95 Ang.
    PLAT417_ALERT_2_B Short Inter D-H..H-D H10A .. H10A .. 1.90 Ang.
这样的B类怎么解决呢?
