求助！！有哪位高手能处理晶体学中CIF里的B类错误!
|

我同学想发一篇晶体学报E让我帮助他可我也不会，想发晶体学报E，有B类错误能发吗？问题是检查时有B类错误如下：Datablock: oy -------------------------------------------------------------------------------- Bond precision: C-C = 0.0062 A Wavelength=0.71073 Cell: a=10.2834(8) b=10.8709(8) c=17.6139(13) alpha=78.680(1) beta=88.197(1) gamma=67.862(1) Calculated Reported Volume 1786.5(2) 1786.5(2) Space group P -1 P-1 Hall group -P 1 ?

PLAT430 Type_2 Test for short non-bonding inter D...A contacts This test alerts for possibly missed Hydrogen bonds as indicated by short (i.e. shorter than sum of the van der Waals radii - 0.2 Angstrom) Donor - Acceptor distances. Note: Short C=O .. O=C are observed sometimes when part of three-centre O-H, N-H or C-H O..O bridging. 望高手不吝赐教！！！也可以发到我的邮箱中wangjiajun002@126.com.cn |
