4-Methoxybenzaldehyde (phthalazin-1-ylidene)hydrazone

Abstract

The title compound, C16H14N4O, crystallizes with two independent mol­ecules in the asymmetric unit. The phthalazin-1-yl and 4-methoxybenzaldehyde groups are coplanar with each other in each of the independent molecules with angles between their mean planes of 15.4 (4) and 13.3 (9)°. The crystal packing is stabilized by inter­molecular N—H⋯N hydrogen bonding between inverted phthalazin-1-yl groups allowing the independent molecules to be stacked in groups oblique to the ab plane in a zigzag pattern.
