Abstract

In the thio­carbonohydrazide mol­ecule of the title compound, C17H12N6O2S·C4H8O, the terminal indolin-2-one ring systems make a dihedral angle of 20.13 (6)° with each other. Two intra­molecular N—H⋯O hydrogen bonds are present, each of which generates an S(6) ring. In the crystal, N—H⋯O hydrogen bonds lead to a mol­ecular chain running along the b axis. The tetra­hydro­furan solvent mol­ecule is disordered over two orientations in a 0.561 (11):0.439 (11) ratio.
