The title compound, C27H19NO2S, contains chains of fused R-2(2)(19) rings formed by intermolecular C-H center dot center dot center dot O=C hydrogen bonds and running along the [011] and [0(1) over bar 1] directions. These chains are linked through short intermolecular C-H center dot center dot center dot pi contacts, giving rise to sheets. The conformation of the title compound is dominated primarily by the nearly orthogonal lone-pair orbitals on the N and S atoms.
