請教一個A類錯誤 已有2人參與

我有一個晶體,基本結構解好,但是最后checkif時有兩個A類錯誤 PLAT411_ALERT_2_A Short Inter H...H Contact H2A .. H22A .. 1.47 Ang. PLAT411_ALERT_2_A Short Inter H...H Contact H4A .. H17A .. 1.78 Ang. PLAT411 Type_2 Test for short non-bonding inter H..H contacts Short intermolecular H..H contacts may indicate incorrectly determined structures (i.e. wrong symmetry, missed translation symmetry, wrong position with reference to the symmetry elements, hydrogen atoms on atoms where there should not be any etc..) Short intermolecular contacts may be indicative for inconsistent symmetry data (e.g. coordinates for space-group P43 and symmetry specified as P41 or P21/n & P21/c confusions). Short contacts are defined using a van der Waals radius of 1.2 Angstrom. For intermolecular contacts, an alert is generated for contacts less than 2.4 Angstrom. 曾嘗試理論加氫以及定Q加氫都未解決,在ins文件中dfix 0.97 0.01 C(?) H(?)dfix 1.37 0.02 H(?) H(?)也未解決,請教大家,這個問題該怎樣解決?謝謝。 |
