Benzyl N'-(1H-indol-2-ylmethyl-ene)hydrazinecarbodithio-ate ethanol hemisolvate

In the crystal of the title compound, C(17)H(15)N(3)S(2)·0.5C(2)H(6)O, the mol-ecules are linked by a pair of N-H(aliphatic)⋯S hydrogen bonds across a center of inversion, forming a dimer. The ethanol solvent mol-ecule, which is statistically disordered about a crystallographic twofold rotation axis, accepts an N-H(aromatic)⋯O hydrogen bond; the hydr-oxy group of the solvent mol-ecule is not engaged in hydrogen bonding.
