PLAT330 Type_2 Check for large average phenyl C-C bond distance value
The standard average C-C bond distance in a phenyl ring is 1.395 Angstrom. The actual average ring distance may be larger than expected due to systematic errors in the unit-cell dimensions (e.g. the use of an incorrect wavelength value for the determination of the unit-cell parameters).
