3-tert-Butyl-2'-chloro-2-hydroxy-5-methylazobenzene

The crystal structure of the title compound, 6-tert-butyl-2-(2-chlorophenyldiazenyl)-4-methylphenol, C₁₇H₁₉ClN₂O, determined at room temperature, shows that the molecule is essentially planar, as found for other azobenzene derivatives, and features a significant intramolecular H...N interaction of 1.75 (3) Å resulting in the formation of a six-membered ring.
