Two solid state phases of 1-bromo-2,4,6-trifluorobenzene, crystallised under non-ambient conditions

Abstract

PhBrF₃, a liquid under ambient conditions, has been crystallised via two different methods, resulting in the formation of non-identical solid-state phases with very similar packing efficiencies but markedly different packing motifs, both of which appear to be directed by classically weak intermolecular halogen–halogen interactions.
