چکیده
The title compound, C(15)H(12)N(2)OS, exists as the thione tautomer in the solid state. The phenyl group is almost perpendicular [dihedral angle = 87.96 (5)°] to the fused ring system (r.m.s. deviation = 0.036 Å for 13 ring and exocyclic non-H atoms). In the crystal, centrosymmetric dimers, sustained by pairs of N-H⋯S hydrogen bonds, are connected into layers parallel to (-101) by C-H⋯O and C-H⋯S inter-actions.
