Abstract
All of the title compounds, C14H8F5N, C14H7F4NO, C13H4F5N and C21H15F3 N2, display a Characteristic stacking of their pi systems in which adj acent members of the stack are related by crystallographic inversion c entres. This leads to a particularly efficient mode of packing in whic h fluorinated rings overlap unfluorinated sections of the molecules at interplanar spacings ranging from 3.40 to 3.51 angstrom.
