PLAT782

 Warning for a possible misassignment of C-NO2 and C-CO2 moieties.  
 The geometry of the reported moiety appears to be unusual/inconsistent.
 The C-O bond distances in C-CO2 are expected to add up to about 2.5
 Test Criteria: ALERT for C-O bond sum < 2.48 and C-C < 1.48 Angstrom   
 The N-O bond distances in C-NO2 are expected to add up to about 2.4
 Test Criteria: ALERT for N-O bond sum > 2.48 and C-C > 1.48 Angstrom
