Crystal structure of 1-[(Z)-2-phenyl-hydrazin-1-yl-idene]naphthalen-2(1H)-one.

In the title compound, C16H12N2O, the dihedral angle between the planes of the benzene ring and naphthalenone ring system is 1.89 (8)°; an intra­molecular N—H⋯O hydrogen bond occurs between the imino group and the carbonyl group. In the crystal, mol­ecules are linked by weak C—H⋯π inter­actions into supra­molecular chains propagating along the [01-1] direction.
