Intra-molecular N-H⋯O and N-H⋯N 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, inter-molecular N-H⋯S hydrogen bonds link the mol-ecules into centrosymmetric dimers. There is a C-H⋯π contact between the naphthalene rings and π-π 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].Acta crystallographica.
