Abstract
The title compound {systematic name: 2-hydroxy-5-[2-(2,4,6-tribromophenyl)diazen-1-yl]cyclohepta-2,4,6-trien-1-one}, C13H7Br3N2O2, is essentially planar, with an r.m.s. deviation of 0.054 Å. The molecular structure is fixed in the azo tautomer by intramolecular C—H...N interactions, with O—H...O hydrogen bonds creating linked dimers. Charge-transfer interactions are observed, with the segregated stacks linked by Br...Br interactions.
