In the title compound C14H15NO (systematic name: 1-n-propylaminomethylene-2-naphthalenone), an intramolecular N-H
O hydrogen bond [N
O 2.578 (2), N-H 0.775, H
O 1.936 Å] arises when the hydroxyl-H atom of the Schiff base prepared from 2-hydroxy-1-naphthaldehyde and n-propylamine shifts to the N atom. This is the consequence of the pronounced quinoidal effect in the 2-oxy-1-naphthaldimine moiety with a very short C3=C4 bond of 1.343 (3) Å. The spatial orientation of the N-substituent with respect to the rest of the molecule (which is planar) depends on the surroundings of the molecules defined by the crystal packing.
