Abstract
A number of novel halogen-bonded aromatic amine cocrystals with 1,4-diiodotetrafluorobenzene have been synthesized via both mechanochemical and solution syntheses, offering valuable insight into potential halogen bond acceptor species.

Halogen bonding relies on the presence of an anisotropically polarized halogen atom, usually bromine or iodine, and its interaction with an electron-rich region on another atom, the halogen bond acceptor.[1]
The selected amines substituted with halogen bond acceptor species are useful compounds from a crystal engineering standpoint, since can they participate in the formation of halogen bonds and of hydrogen bonds with the donor amino group
Summary
A number of novel halogen-bonded aromatic amine cocrystals with 1,4-diiodotetrafluorobenzene have been synthesized via both mechanochemical and solution syntheses, offering valuable insight into potential halogen bond acceptor species. The selected amines substituted with halogen bond acceptor species (a nitro, a pyridine, a carbonyl, a nitrile or a methoxy group) are useful compounds from a crystal engineering standpoint, since can they participate in the formation of halogen bonds and of hydrogen bonds with the donor amino group.
