The conformation of the tetrahydropyrimidine ring is that of a distorted boat. In the crystal structure, N—HO hydrogen bonds form molecular dimers and also link these dimers into chains along the c axis of the unit cell.
organic compounds
The title compound, C9H14N2O2S, belongs to a group of esters of 2-oxo- and 2-thioxo-1,2,3,4-tetrahydropyrimidine-5-carboxylic acids, which exhibit a wide spectrum of biological activities. The conformation of the pyrimidine ring is a distorted boat. In the crystal structure, hydrogen-bonded centrosymmetric dimers are formed via intermolecular N—HS hydrogen bonds. The dimers are linked by intermolecular N—HO hydrogen bonds to form a two-dimensional network.
