4-(Diphenyl-amino)-benzaldehyde 4-phenyl-thio-semicarbazone.

ABSTRACT: The title mol-ecule, C(26)H(22)N(4)S, is composed of three main parts, viz. a triphenyl-amine group is connected to a phenyl ring by a thio-semicarbazone moiety. The C= N double bond has an E conformation. The crystal packing is dominated by strong hydrogen bonds through the thio-semicarbazone moiety, with pairs of N-H?S hydrogen bonds linking the mol-ecules to form inversion dimers with an R(2) (2)(8) ring motif. An intra-molecular N-H?N hydrogen bond is also present, generating an S(5) ring motif. Although the structure contains four phenyl rings, ?-? stacking inter-actions are not formed between them, probably due to the conformation adopted by the triphenyl-amine group. However, a weak ?-? stacking inter-action is observed between the phenyl ring and the delocalized thio-semicarbazone moiety.
