Abstract

In the N-substituted benzoyl-thio-urea, C(24)H(23)N(5)OS, the benzoyl-thio-urea unit is non-planar (r.m.s. deviation = 0.126 Å). The aliphatic part of the tetra-hydro-quinoline fused-ring system is disordered over two positions in a 0.592 (5):0.408 (5) ratio. The pyridine and pyrrole rings are twisted by 55.2 (1)° in order to avoid crowding of their respective substituents. Pairs of mol-ecules are linked by N-H⋯N hydrogen bonds, forming centrosymmetric dimers. Furthermore, an intra-molecular N-H⋯O hydrogen bond stabilizes the mol-ecular conformation.
