Alert level A
PLAT029_ALERT_3_A _diffrn_measured_fraction_theta_full Low .......       0.93
Author Response: Even though crystal data was collected up to 28.81 degrees (which is higher than the required 25.24 degrees for MoKa radiation), the selected single-crystal (the largest from several batches) diffracted weakly at high angles. 

Alert level C
REFLT03_ALERT_3_C  Reflection count < 95% complete
           From the CIF: _diffrn_reflns_theta_max           28.81
           From the CIF: _diffrn_reflns_theta_full          28.81
           From the CIF: _reflns_number_total               3994
           TEST2: Reflns within _diffrn_reflns_theta_max
           Count of symmetry unique reflns         4316
           Completeness (_total/calc)             92.54%
Author Response: Please, see our response to _vrf_PLAT029. 
PLAT200_ALERT_1_C Check the Reported _diffrn_ambient_temperature .        293 K
Author Response: Data was indeed collected at ambient temperature. 
PLAT705_ALERT_1_C D-H     Calc   0.828(10), Rep     0.84(2), Dev..       1.20 Sigma 
              O1W  -H1C     1.555   1.555                                       


Alert level G
ABSTM02_ALERT_3_G  The ratio of expected to reported Tmax/Tmin(RR') is < 0.90
            Tmin and Tmax reported:      0.354     0.724
            Tmin(prime) and Tmax expected:      0.458     0.784
            RR(prime) =      0.838
            Please check that your absorption correction is appropriate.


   1 ALERT level A = In general: serious problem
   0 ALERT level B = Potentially serious problem
   3 ALERT level C = Check and explain
   1 ALERT level G = General alerts; check

   2 ALERT type 1 CIF construction/syntax error, inconsistent or missing data
   0 ALERT type 2 Indicator that the structure model may be wrong or deficient
   3 ALERT type 3 Indicator that the structure quality may be low
   0 ALERT type 4 Improvement, methodology, query or suggestion
