The asymmetric unit of the title compound, C25H21N3O2S, comprises four molecules. Their conformations differ primarily in the orientations of the styryl and the N-phenylcarboxamido groups. In the crystal, intermolecular N-H center dot center dot center dot N, C-H center dot center dot center dot O and C-H center dot center dot center dot S hydrogen-bonding contacts as well a C-H center dot center dot center dot pi(ring) interactions lead to the formation of a layer structure parallel to (010). Hirshfeld surface analysis revealed that H center dot center dot center dot H interactions represent the main contributions to the crystal packing.
