1-(4-tert-Butyl-benz-yl)pyrimidine-2,4(1H,3H)-dione.

ABSTRACT: The asymmetric unit of the title compound, C(15)H(18)N(2)O(2), contains two independent mol-ecules with essentially identical geometries and conformations. The dihedral angles between the benzene and pyrimidine rings in the two mol-ecules are 89.96?(11) and 73.91?(11)°. The six methyl groups are disordered over two sets of sites, with site occupancies of 0.545?(4):0.455?(4) and 0.542?(7):0.458?(7) in the two mol-ecules. The crystal structure is stabilized by N-H?O hydrogen bonds.

The asymmetric unit of the title compound, C(15)H(18)N(2)O(2), contains two independent mol-ecules with essentially identical geometries and conformations.

Project description: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.

6-(3,5-Dimethyl-benz-yl)-5-ethyl-1-[(2-phenyl-eth-oxy)meth-yl]pyrimidine-2,4(1H,3H)dione.

Project description:In the title pyrimidine derivative, C(24)H(28)N(2)O(3), the uracil unit is essentially planar with an r.m.s. deviation of 0.0054 (1) Å for the eight non-H atoms. The pyrimidine ring is tilted by a dihedral angle of 77.08 (7)° with respect to the aromatic ring of the 3,5-dimethyl-benzyl substituent, whereas it is nearly parallel to the benzene ring of the pheneth-oxy-methyl unit, with a dihedral angle of 8.17 (8)°. An intra-molecular C-H⋯O hydrogen bond generates an S(6) ring motif. In the crystal, mol-ecules are linked by a pair of amide-uracil N-H⋯O hydrogen bonds into an inversion R(2) (2)(8) dimer. These dimers are stacked along the b axis through π-π inter-actions with a centroid-centroid distance of 3.9517 (8) Å. Weak C-H⋯π inter-actions are also present.

5-Fluoro-1-(3-metylbutano-yl)pyrimidine-2,4(1H,3H)-dione.

Project description:The 3-methyl-butanoyl group and the 5-fluoro-uracil unit of the title compound, C(9)H(11)FN(2)O(3), are essentially coplanar, with the carbonyl group oriented towards the ring CH group and away from the nearer ring carbonyl group. The 3-methyl-butanoyl (C=)C-N-C=O torsion angle of 9.6?(2)° is comparable to that in structurally related compounds. In the solid state, two inversion-related mol-ecules form N-H?O hydrogen bonds to generate an inter-molecular R(2) (2)(8) ring. The crystal structure also diplays intra- and inter-molecular C-H?O inter-actions.

Project description:In the title pymiridine-2,4-dione derivative, C14H16N2O2S, the dihedral angle between the six-membered rings is 66.69?(10)°.

Quinazoline-2,4(1H,3H)-dione.

Project description:In the title compound, C(8)H(6)N(2)O(2), inter-molecular N-H?O hydrogen bonds involving the amine and carbonyl groups create centrosymmetric dimers between adjacent nearly coplanar mol-ecules. These dimers are further connected by weak N-H?O hydrogen bonds, forming a two-dimensional network. Mol-ecules are packed in the crystal structure with adjacent benzene and pyrimidine rings approximately coplanar; the centroid-centroid separation is 3.863?Å and the dihedral angle between the mean planes is 0.64°, indicating the presence of weak inter-molecular face-to-face ?-? stacking inter-actions.
