3-Amino-4-[4-(Dimethyl-Amino)-Phen-yl]-4,5-Dihydro-1,2,5-Thia-Diazole 1,1-Dioxide

Abstract

The title compound, C <inf>10</inf>H <inf>14</inf>N <inf>4</inf>O <inf>2</inf>S, exists in the amine tautomeric form. The dihedral angle between the benzene and thia-diazo-lidine rings is 66.54 (19)°. In the crystal, mol-ecules are linked by N - H⋯O and N - H⋯N hydrogen bonds into a layer parallel to the ac plane. The layers are further linked by C - H⋯O hydrogen bonds. © Arslan et al. 2011.
