✦ Synopsis

In the title molecule, C 23 H 17 N 3 O 2 , intramolecular O-HÁ Á ÁO and N-HÁ Á ÁN hydrogen bonds influence the molecular conformation. In the crystal structure,interactions, with a distance of 3.611 (5) A ˚between the centroids of rings in neighbouring naphthalene rings, link the molecules into centrosymmetric dimers, and C-HÁ Á Á interactions link the dimers into chains running in the [101] direction.
