title: (Z)-4-(3-Fluoro-phen-yl)-1-(5-nitro-2-oxo-indolin-3-yl-idene)thio-semicarbazide.
abstract: In the title compound, C(15)H(10)FN(5)O(3)S, an intra-molecular N-H⋯N hydrogen bond generates an S(5) ring, whereas N-H⋯O and C-H⋯S inter-actions complete S(6) ring motifs. The dihedral angle between the isatin ring system and the fluoro-benzene ring is 5.96 (6)° and the complete mol-ecule is close to planar (r.m.s. deviation for all the non-H atoms = 0.112 Å). In the crystal, mol-ecules are linked by N-H⋯O hydrogen bonds to form C(8) chains along the [100] direction and C-H⋯O inter-actions are also observed.
