4-Ethyl-2-(2-hydroxynaphthylmethylidene)amino-5-methyl-3-thiophenecarbonitrile

The crystal structure of the title compound, C₁₉H₁₆N₂OS, has been determined. The core of the mol­ecule (excluding the methyl group) is planar, with the largest deviation of 0.069 (2) Å for the O atom. An intra­molecular O—H...N-type hydrogen bond occurs between the hydroxyl and amino groups [2.574 (3) Å].
