呼唤xi2004:cifcheck很多的警告,请问结构还要怎么精修
|
|||
|
我这个晶体是通过固态反应得到的,晶体质量不好,收了几次了也都这样。请问目前怎么做能尽量减少警告,有的能解释下也行。现在文章在修改中,编辑能重新修下这个结构。 PLAT029_ALERT_3_A _diffrn_measured_fraction_theta_full Low ....... 0.78 PLAT213_ALERT_2_A Atom N8 has ADP max/min Ratio ............. 7.90 prola PLAT213_ALERT_2_A Atom C12 has ADP max/min Ratio ............. 8.60 prola PLAT213_ALERT_2_A Atom C17 has ADP max/min Ratio ............. 5.10 prola PLAT220_ALERT_2_A Large Non-Solvent N Ueq(max)/Ueq(min) ... 6.33 Ratio PLAT601_ALERT_2_A Structure Contains Solvent Accessible VOIDS of . 253.00 A**3 --------------------------------------------------------------------------------Alert level B REFLT03_ALERT_1_B Reflection count < 90% complete (theta max?)

PLAT029_ALERT_3_A _diffrn_measured_fraction_theta_full Low ....... 0.78 这是硬伤,我想很难有办法的 PLAT213_ALERT_2_A Atom N8 has ADP max/min Ratio ............. 7.90 prola PLAT213_ALERT_2_A Atom C12 has ADP max/min Ratio ............. 8.60 prola PLAT213_ALERT_2_A Atom C17 has ADP max/min Ratio ............. 5.10 prola PLAT220_ALERT_2_A Large Non-Solvent N Ueq(max)/Ueq(min) ... 6.33 Ratio 可能是潜在的无序或数据差造成的,可处理,但较麻烦 PLAT601_ALERT_2_A Structure Contains Solvent Accessible VOIDS of . 253.00 A**3 这个不算太大的问题,解释一下还能通过 |
