3-[2-(4,4-Dimethyl-2,6-dioxocyclohexylidene)hydrazinyl]benzonitrile

Abstract

The title compound, C15H15N3O2, contains benzonitrile and 4,4-dimethyl-2,6-dioxocyclohexylidene groups connected via a hydrazinyl group. The structure is in the hydrazone tautomeric form in the solid state. The benzonitrile and hydrazinyl groups (3-hydrazinylbenzonitrile) are essentially coplanar with an r.m.s. deviation of 0.016 Å. Intramolecular N—H...O hydrogen bonding helps to stabilize the molecular structure, and weak intermolecular C—H...O hydrogen bonding is present in the crystal structure.
