Abstract

The title crystals, C7H2I3N, are isomorphous. Both molecules lie across two crystallographic mirror planes and a twofold axis. The principal supramolecular interaction is centric R22(10) CN/NC I short contacts involving both ortho I atoms, with two contacts bisecting each cyano and isocyano group. These form ribbons along [010] and give rise to a planar sheet structure parallel to (100). All pairs of adjacent sheets have centric stacking, a mode not previously reported for sheets of this type. This study completes the series of homo-2,4,6trihalobenzonitriles, in which I atoms give the strongest CN X and NC X interactions (X = F, Cl, Br, I).
