The crystal structure of the title compound, C(12)H(11)NO(2), represents a new ortho-rhom-bic polymorph II of the previously reported ortho-rhom-bic form I [Zhang et al. (2009 ▶) Acta Cryst. E65, o3160]. In polymorph II, the six-membered rings form a dihedral angle of 13.8 (1)° [71.6 (1)° in I], and O-H⋯N hydrogen bonds link mol-ecules into chains along [100], whereas the crystal structure of I features hydrogen-bonded centrosymmetric dimers.
