Alert level B PLAT241_ALERT_2_B Check High Ueq as Compared to Neighbors for C19
Alert level C ABSTM02_ALERT_3_C The ratio of expected to reported Tmax/Tmin(RR') is < 0.90 Tmin and Tmax reported: 0.799 1.000 Tmin(prime) and Tmax expected: 0.938 0.977 RR(prime) = 0.833 Please check that your absorption correction is appropriate. Value of measurement temperature given = 293.000 Value of melting point given = 0.000 PLAT220_ALERT_2_C Large Non-Solvent C Ueq(max)/Ueq(min) ... 2.63 Ratio PLAT230_ALERT_2_C Hirshfeld Test Diff for C3 -- C4 .. 5.83 su PLAT232_ALERT_2_C Hirshfeld Test Diff (M-X) Al1 -- C7 .. 5.31 su PLAT241_ALERT_2_C Check High Ueq as Compared to Neighbors for C16 PLAT242_ALERT_2_C Check Low Ueq as Compared to Neighbors for O1 PLAT061_ALERT_4_C Tmax/Tmin Range Test RR' too Large ............. 0.83 PLAT062_ALERT_4_C Rescale T(min) & T(max) by ..................... 0.98
Alert level G ABSTM02_ALERT_3_G When printed, the submitted absorption T values will be replaced by the scaled T values. Since the ratio of scaled T's is identical to the ratio of reported T values, the scaling does not imply a change to the absorption corrections used in the study. Ratio of Tmax expected/reported 0.977 Tmax scaled 0.977 Tmin scaled 0.781 PLAT199_ALERT_1_G Check the Reported _cell_measurement_temperature 293 K PLAT200_ALERT_1_G Check the Reported _diffrn_ambient_temperature . 293 K
