Abstract: In the molecule of the title compound, C30H22N4O2S2, the central benzene ring is oriented at dihedral angles of 63.83 (3) and 1.37 (3)° with respect to the naphthalene ring systems, while the two naphthalene ring systems are oriented at a dihedral angle of 62.78 (3)°. Intramolecular N-HO and N-HN hydrogen bonds result in the formation of one five- and two six-membered rings. The twisting modes of the two side arms are different [C-N-C-O and C-N-C-N torsion angles = 11.1 (4) and 1.5 (3)°, respectively, in one arm, and -2.2 (4) and 0.8 (3)° in the other arm]. In the crystal structure, intermolecular N-HS hydrogen bonds link the molecules into centrosymmetric dimers. There is a C-H contact between the naphthalene rings and - contacts between the naphthalene rings and the naphthalene and benzene rings [centroid-centroid distances = 3.651 (1), 3.828 (1), 3.811 (2) and 3.786 (1) Å].
