A redetermination of 1-{4-[(2-hydroxy­benzyl­idene)­amino]­phenyl}ethano­ne

The crystal structure of the title compound, C₁₅H₁₃NO₂, has been redetermined with better precision and with the location and free refinement of all H atoms [previous report; Rekhlova, Furmanova, Chanturiya & Chikhladze (1991). Kristallografiya, 36, 117–120]. The mol­ecule is present as the phenol–imine tautomeric form with strong intramolec­ular O—H⋯N hydrogen bonds.
