rac-6-Hydroxy-4-(4-nitrophenyl)-5-(2-thienylcarbonyl)-6-(trifluoromethyl)-3,4,5,6-tetrahydropyrimidin-2(1H)-one monohydrate
The title compound, C(16)H(12)F(3)N(3)O(5)S·H(2)O, was prepared by reaction of 4-nitro-benzaldehyde, 4,4,4-trifluoro-1-(thio-phen-2-yl)butane-1,3-dione and urea. The asymmetric unit contains two independent mol-ecules, with essentially identical geom-etries and conformations. The dihydro-pyrimidine rings adopt a half-chair conformation. The dihedral angles between the benzene ring and the thio-...

The asymmetric unit of the title compound, C(16)H(12)ClF(3)N(2)O(3)S·H(2)O, contains two crystallographically independent organic mol-ecules and two water mol-ecules. The organic species are linked by an inter-molecular O-H⋯O hydrogen bond, while the water mol-ecules are connected to them through inter-molecular O-H⋯N hydrogen bonds. The thio-phene and phenyl rings are oriented at dihedral angl...

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 linke...

The asymmetric unit of the title compound, C(14)H(14)F(4)N(2)O(4)·H(2)O, contains two crystallographically independent organic mol-ecules and two water mol-ecules. The two 1,3-diazinane rings adopt a half-chair conformation and the dihedral angles between their mean planes and those of the benzene rings are 75.65 (4)° and 49.41 (3)° in the two mol-ecules. The crystal structure is stabilized by ...
متن کامل2-(4-Chlorophenyl)-6-methoxychroman-4-one
In the title mol-ecule, C(16)H(13)Cl O(3), the two aromatic rings form a dihedral angle of 65.3 (1)°. In the crystal structure, weak inter-molecular C-H⋯O hydrogen bonds link the mol-ecules into centrosymmetric dimers, which are further packed into columns propagating in [100] by weak C-H⋯π inter-actions.
