In the title compound, C 16 H 16 N 2 O 4 Á0.5CH 3 CH 2 OH, the Schiff base is approximately planar. An intramolecular N-HÁ Á ÁO hydrogen bond stabilizes the molecular structure. The molecules are linked by O-HÁ Á ÁO hydrogen bonds to form a chain along the b axis.

The vanillin residue makes dihedral angles of 4.84 (18) and 11.96 (7) with the planes of the butyl group and the terminal benzene ring, respectively. Intermolecular N-HÁ Á ÁO and C-HÁ Á ÁO hydrogen bonds help to consolidate the crystal packing.
