The title compound, C20H11N3S, crystallizes with two molecules in the asymmetric unit. The molecules are non-planar, with a central ring in a boat conformation. The dihedral angle between the least-squares planes of the benzo rings fused to the central ring is 44.6(1)degrees in one molecule, and 50.1(1)degrees in the other.
