摘要

The title compound {systematic name: 2-hy#173;droxy-5-2-(2,4,6-tri#173;bromo#173;phen#173;yl)diazen-1-ylcyclo#173;hepta-2,4,6-trien-1-one}, C13H7Br3N2O2, is essentially planar, with an r.m.s. deviation of 0.054#8197;#197;. The mol#173;ecular structure is fixed in the azo tautomer by intra#173;molecular C#8212;H#8943;N inter#173;actions, with O#8212;H#8943;O hydrogen bonds creating linked dimers. Charge-transfer inter#173;actions are observed, with the segregated stacks linked by Br#8943;Br inter#173;actions.
