In the crystal of the title compound, C17H15N3S2·0.5C2H6O, the molecules are linked by a pair of N—Haliphatic⋯S hydrogen bonds across a center of inversion, forming a dimer. The ethanol solvent molecule, which is statistically disordered about a crystallographic twofold rotation axis, accepts an N—Haromatic⋯O hydrogen bond; the hydroxy group of the solvent molecule is not engaged in hydrogen bonding.

Indole-2-carbaldehyde (0.36 g, 2.5 mmol) and S-benzyldithiocarbazate (0.495 g, 2.5 mmol) were heated in ethanol (40 ml) for 3 h. The solution was set aside for the formation of yellow blocks of (I).
C-bound hydrogen atoms were placed at calculated positions (C–H = 0.95–0.99 Å) and refined as riding with U(H) = 1.2–1.5 times Ueq(C). The amino and hydroxy H atoms were located in a difference map, and were refined with distance restraints of N–H = 0.88±0.01 and O–H = 0.84+_0.01 Å; their Uiso values were freely refined.
The ethanol molecule is statistically disordered about a two-fold axis: the O–C distance was restrained to 1.45±0.01 Å and the C–C distance to 1.50+_0.01 Å; the displacement factors of the two C atoms were restrained to be equal.
