title: 1-(1-Nonyl-2-oxoindolin-3-yl-idene)thio-semicarbazide.
abstract: In the title compound, C(18)H(26)N(4)OS, the imine C=N bond has a Z configuration, whereas the N-N-C=S unit has an E conformation. In the crystal, mol-ecules are connected through N-H⋯O hydrogen bonds, forming zigzag chains running along the b axis. The nonyl chain adopts an extended zigzag conformation.
