6-(Trifluoromethyl)pyrimidine-2,4(1H,3H)-dione monohydrate
The title compound, C(5)H(3)F(3)N(2)O(2)·H(2)O, was prepared by the reaction of ethyl 4,4,4-trifluoro-3-oxobutano-ate with urea. In the crystal, the 6-(trifluoro-meth-yl)pyrimidine-2,4(1H,3H)-dione and water mol-ecules are linked by N-H⋯O and O-H⋯O hydrogen bonds. A ring dimer structure is formed by additional inter-molecular N-H⋯O hydrogen bonds.

The title compound, C(24)H(14)O(9)·H(2)O, displays a cup-shaped form. The water mol-ecule is disordered over two set of sites with an occupancy ratio of 0.78:0.22. The mol-ecule of the compound has four stereocenters and corresponds to the SSRR/RRSS diastereoisomer. In the mol-ecule, the maximum dihedral angle between the planar benzene rings is 80.40 (4)°. The H atoms of the hy-droxy groups ar...
