不知A類(lèi)問(wèn)題是否加描述 C與G不明白。非常謝謝 Alert level A EXPT005_ALERT_1_A _exptl_crystal_description is missing Crystal habit description. The following tests will not be performed. CRYSR_01 EXPT010_ALERT_1_A _exptl_crystal_colour (_pd_char_colour for powder) is missing Crystal colour. The following tests will not be performed. Alert level C ABSTY02_ALERT_1_C An _exptl_absorpt_correction_type has been given without a literature citation. This should be contained in the _exptl_absorpt_process_details field. Absorption correction given as multi-scan CHEMW03_ALERT_2_C The ratio of given/expected molecular weight as calculated from the _atom_site* data lies outside the range 0.99 <> 1.01 From the CIF: _cell_formula_units_Z 4 From the CIF: _chemical_formula_weight 890.62 TEST: Calculate formula weight from _atom_site_* atom mass num sum C 12.01 49.40 593.34 H 1.01 28.00 28.22 N 14.01 4.00 56.03 O 16.00 5.00 79.99 Fe 55.85 2.00 111.69 Calculated formula weight 869.28 PLAT041_ALERT_1_C Calc. and Reported SumFormula Strings Differ ?
