چکیده
The title compound, C(19)H(24)N(2)O(2), adopts the phenol-imine tautomeric form. An intra-molecular O-H⋯N hydrogen bond results in the formation of a six-membered ring. The aromatic rings are oriented at a dihedral angle of 17.33 (16)°. Inter-molecular C-H⋯π inter-actions occur in the crystal.

The title compound, C(18)H(21)N(3)O(3), is a potential bidentate Schiff base ligand. The whole mol-ecule is disordered with a refined site-occupancy ratio of 0.567 (4):0.433 (4) and not just one ethyl group as reported previously [Sarojini et al. (2007 ▶). Acta Cryst. E63, o4782-o4782]. Using the whole mol-ecule disorder, R values are much smaller than those published. An intra-molecular O-H⋯N ...
