1-Methylindole-2-carbaldehyde (0.40 g, 2.5 mmol) and S-benzyldithiocarbazate (0.50 g, 2.5 mmol) were heated in ethanol (40 ml) for 3 h. The solid that separated on cooling the solution was collected and recrystallized from ethanol and washed with cold ethanol and dried. Orange prisms of (I) were grown by slow evaporation of ethanol solution at room temperature.
Hydrogen atoms were placed at calculated positions (C–H = 0.95–0.99, N–H = 0.88Å) and refined as riding with U(H) = 1.2–1.5 times Ueq(C,N).
The largest difference peak is close to S2.
