Abstract: In the crystal of the title salt, C6H7N2S+·I-, inversion-related cations form an R22(8) dimer linked by a pair of N-HS hydrogen bonds. Pairs of iodide anions are located between adjacent cation dimers and are linked to them by way of N-HI hydrogen bonds. This results in zigzag chains propagating in  lying parallel to the bc plane.
