Co-crystals of iodopentafluorobenzene with nitrogen donors: 2-D molecular assemblies through halogen bonding and aryl–perfluoroaryl interactions

Abstract

Electron deficient iodopentafluorobenzene forms heterodimers with electron rich pyridine donors stabilized by halogen bonding, that are further assembled into polar brick-wall type 2-D network via π–π stacking interactions between aryl and perfluoroaryl moieties.
