چکیده
The title compound, C(17)H(16)N(4)OS, is stabilized in the form of a two-dimensional polymeric network due to inter-molecular N-H⋯S and N-H⋯O hydrogen bonds. An intra-molecular N-H⋯N hydrogen bond forms an S(5) ring, whereas inter-actions of the N-H⋯O and C-H⋯S types complete S(6) ring motifs. π-π inter-actions with a centroid-centroid distance of 3.6514 (10) Å are found between the ethyl-substituted benzene ring and the heterocyclic ring of the isatin derivative.

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.
