title: (Z)-N-Ethyl-2-(5-fluoro-2-oxoindolin-3-yl-idene)hydrazinecarbothio-amide.
abstract: In the title compound, C(11)H(11)FN(4)OS, an intra-molecular N-H⋯O hydrogen bond generates an S(6) ring. In the crystal, mol-ecules form chains through N-H⋯O hydrogen bonds, which are extended by N-H⋯S hydrogen bonds into an infinite three-dimensional network.
