Abstract
AbstractThe influence of intramolecular hydrogen bonds and steric hindrance on distortion from planarity of the benzene ring and its aromaticity is shown for a series of substituted 2,4,6‐trinitroanilines. The crystal structure geometry and thegeometry optimized at the B3LYP/6‐311++G** level are compared with analogues without intramolecular hydrogen bonds. The HOMA index and the parameter ΔP describing the distortion from planarity of the benzene ring were used to characterize the aromacity of the investigated molecules. NBO and AIM analysis were also applied.
