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-HN 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.
