4,5-Diazafluoren-9-one benzoylhydrazone monohydrate.

The title compound, C(18)H(12)N(4)O.H(2)O, adopts the keto tautomeric form and the azomethine C=N double bond is in the E configuration. The dihedral angle between the planes of the diazafluorene moiety and the phenyl ring is 11.3 (1) degrees. In the solid state, the molecules form infinite chain-like structures via O-H.N hydrogen bonds involving the water molecules and diazafluorene moieties.
