Abstract
In the title compound, C9H10N3S+·NO3-, the indole ring system and the thiouronium group are nearly perpendicular, with a dihedral angle of 88.62 (6)°. Hydrogen bonding generates two-dimensional networks which are linked to each other via [pi] stacking interactions of the indole groups [average inter-planar ring-ring distance of 3.449 (2) Å].
