Sumario:The title mol­ecule, C(26)H(22)N(4)S, is composed of three main parts, viz. a triphenyl­amine group is connected to a phenyl ring by a thio­semicarbazone moiety. The C= N double bond has an E conformation. The crystal packing is dominated by strong hydrogen bonds through the thio­semicarbazone moiety, with pairs of N—H⋯S hydrogen bonds linking the mol­ecules to form inversion dimers with an R (2) (2)(8) ring motif. An intra­molecular N—H⋯N hydrogen bond is also present, generating an S(5) ring motif. Although the structure contains four phenyl rings, π–π stacking inter­actions are not formed between them, probably due to the conformation adopted by the triphenyl­amine group. However, a weak π–π stacking inter­action is observed between the phenyl ring and the delocalized thio­semicarbazone moiety.
