Abstract
The essential part (including all the non-hydrogen atoms except two methyl carbons) of the mol-ecule of the title compound, C
H
N
O
, lies on a mirror plane, which bis-ects the
-butyl groups. The conformation of the C=N bond of this Schiff base compound is
, and there is an intra-molecular N-H⋯O hydrogen bond present, forming an
(6) ring motif. In the crystal, mol-ecules are linked
O-H⋯O hydrogen bonds, forming zigzag chains propagating along the
axis direction. There are no other significant inter-molecular contacts present.
