6-(Trifluoromethyl)pyrimidine-2,4(1H,3H)-dione monohydrate

Abstract

The title compound, C5H3F3N2O2·H2O, was prepared by the reaction of ethyl 4,4,4-trifluoro-3-oxobutanoate with urea. In the crystal, the 6-(trifluoromethyl)pyrimidine-2,4(1H,3H)-dione and water molecules are linked by N—H...O and O—H...O hydrogen bonds. A ring dimer structure is formed by additional intermolecular N—H...O hydrogen bonds.
