title: 5-Benzoyl-4-hydr-oxy-6-(4-nitro-phen-yl)-4-trifluoro-meth-yl-3,4,5,6-tetrahydro-pyrimidin-2(1H)-one monohydrate.
abstract: The asymmetric unit of the title compound, C(18)H(14)F(3)N(3)O(5)·H(2)O, contains two independent formula units. The two heterocyclic mol-ecules differ in the orientations of the benzoyl-phenyl group with respect to the tetra-hydro-pyrimidine ring [C-C-C-C torsion angles of 64.5 (3) and 67.1 (3)°]. In both mol-ecules the pyrimidine ring adopts a half-chair conformation. The mol-ecules are linked into a two-dimensional network parallel to (001) by N-H⋯O and O-H⋯O hydrogen bonds.
