我不是做单晶的，在checkcif时出现了A，B，C，G错误。希望得到大神指点。 Alert level A CHEMW03_ALERT_2_A ALERT: The ratio of given/expected molecular weight as calculated from the _atom_site* data lies outside the range 0.90 <> 1.10 From the CIF: _cell_formula_units_Z 132 From the CIF: _chemical_formula_weight 186.00 TEST: Calculate formula weight from _atom_site_* atom mass num sum C 12.01 1.36 16.38 H 1.01 2.45 2.47 O 16.00 0.41 6.55 Calculated formula weight 25.40 PLAT029_ALERT_3_A _diffrn_measured_fraction_theta_full value Low . 0.720 Note PLAT043_ALERT_1_A Calculated and Reported Mol.
