不懂
幫頂一下
空間群轉(zhuǎn)換一下 該填該改的好像都沒改一些氫假的好像也不對
你的Z值不對,
PLAT430_ALERT_2_A Short Inter D...A Contact O20 .. O21 .. 2.43 Ang.
你可以在ins文件用dfix 2.80 (嘗試比2.43大的數(shù)) O20 O21
PLAT761_ALERT_1_A CIF Contains no X-H Bonds ...................... ?
PLAT762_ALERT_1_A CIF Contains no X-Y-H or H-Y-H Angles .......... ?
你可以在ins文件添加bond $h指令,XL-XL精修
游離O上沒加氫,加上
多修幾輪
ABSTM02_ALERT_3_A The ratio of Tmax/Tmin expected RT(exp) is > 1.30
An absorption correction should be applied.
Tmin and Tmax expected: 0.059 0.122
RT(exp) = 2.066
要做合適的吸收矯正
From the CIF: _cell_formula_units_Z 25
Z值沒有這么大的,要重新算,改過來
SHFSU01_ALERT_2_A The absolute value of parameter shift to su ratio > 0.20
Absolute value of the parameter shift to su ratio given 1.139
Additional refinement cycles may be required.
PLAT080_ALERT_2_A Maximum Shift/Error ............................ 1.14
再修不止100輪

PLAT306_ALERT_2_A Isolated Oxygen Atom (H-atoms Missing ?) ....... O21
PLAT306_ALERT_2_A Isolated Oxygen Atom (H-atoms Missing ?) ....... O22
水上沒加氫,能加則加,不能說明一下即可
結(jié)構(gòu)解完可能還需要一段時間,一點一點處理,
剛接觸,不是很懂,路過,長長人氣
