Abstract

In the title pymiridine-2,4-dione derivative, C14H16N2O2S, the dihedral angle between the six-membered rings is 66.69 (10)°. The mol-ecule is twisted about the Cp-S (p = pyrimidine) bond, with a C-S-C-N torsion angle of -19.57 (16)°. In the crystal, adjacent mol-ecules form inversion dimers through pairs of strong N-H⋯O hydrogen bonds, generating an R 2 (2)(8) ring motif. The dimers are connected into chains extending along the c-axis direction through additional N-H⋯O hydrogen bonds.
