In the title compound, C(15)H(11)IN(4)OS, intra-molecular N-H⋯N, N-H⋯O and C-H⋯S inter-actions generate one S(5) and two S(6) ring motifs. In the crystal, mol-ecules form centrosymmetric dimers via pairs of N-H⋯O inter-actions, generating R(2) (2)(8) ring motifs. In addition a short inter-molecular I⋯S contact of 3.352 (3) Å is observed.
