1,3-Bis(4-methyl-benz-yl)pyrimidine-2,4(1H,3H)-dione.

ABSTRACT: In the title mol-ecule, C(20)H(20)N(2)O(2), the central pyrimidine ring forms dihedral angles of 71.9?(1) and 69.8?(1)° with the two benzene rings. In the crystal, weak inter-molecular C-H?O hydrogen bonds link mol-ecules into centrosymmetric dimers. The crystal packing exhibits also ?-? inter-actions as indicated by short distances of 3.674?(2)?Å between the centroids of the pyrimidine rings of neighbouring mol-ecules.

In the title mol-ecule, C(20)H(20)N(2)O(2), the central pyrimidine ring forms dihedral angles of 71.9 (1) and 69.8 (1)° with the two benzene rings. In the crystal, weak inter-molecular C-H⋯O hydrogen bonds link mol-ecules into centrosymmetric dimers. The crystal packing exhibits also π-π inter-actions as indicated by short distances of 3.674 (2) Å between the centroids of the pyrimidine rings of neighbouring mol-ecules. ...[more]

(E)-6-Amino-1,3-dimethyl-5-[(pyridin-2-yl-methyl-idene)amino]-pyrimidine-2,4(1H,3H)-dione.

Project description:In the title compound, C(12)H(13)N(5)O(2), a Schiff-base-derived chelate ligand, the non-aromatic heterocycle and its substituents essentially occupy one common plane (r.m.s. of fitted non-H atoms = 0.0503 Å). The N=C bond is E-configured. Intra-cyclic angles in the pyridine moiety cover the range 117.6 (2)-124.1 (2)°. Intra- and inter-molecular N-H⋯N and N-H⋯O hydrogen bonds are observed in the crystal structure, as are intra- and inter-molecular C-H⋯O contacts which, in total, connect the mol-ecules into a three-dimensional network. The shortest ring-centroid-to-ring-centroid distance of 3.5831 (14) Å is between the two different types of six-membered rings.

6-[(Dimethyl-amino)methyl-ene-amino]-1,3-dimethyl-pyrimidine-2,4(1H,3H)-dione dihydrate.

Project description:Uracil, the pyrimidine nucleobase, which combined with adenine forms one of the major motifs present in the biopolymer RNA, is also involved in the self-assembly of RNA. In the title compound, C(9)H(14)N(4)O(2)·2H(2)O, the asymmetric unit contains one dimethyl-amino-uracil group and two water mol-ecules. The plane of the N=C-NMe(2) side chain is inclined at 27.6?(5)° to the plane of the uracil ring. Both water mol-ecules form O-H?O hydrogen bonds with the carbonyl O atoms of the uracil group. Additional water-water hydrogen-bond inter-actions are also observed in the crystal structure. The O-H?O hydrogen bonds lead to the formation of a two-dimensional hydrogen-bonded network cage consisting of two dimethyl-amino-uracil groups and six water mol-ecules.

6-Amino-1,3-dimethyl-5-[(E)-2-(methyl-sulfan-yl)benzyl-idene-amino]-pyrimidine-2,4(1H,3H)-dione.

Project description:The title compound, C(14)H(16)N(4)O(2)S, is a Schiff base derivative of 2-(methyl-sulfan-yl)benzaldehyde. The configuration about the C=N double bond is E. The heterocyclic ring is essentially planar (τ = 3.1°) and makes a dihedral angle of 12.24 (7)° with the benzene ring. An intra-molecular N-H⋯S hydrogen bond is observed. In the crystal, N-H⋯O and C-H⋯O hydrogen bonds link mol-ecules into layers perpendicular to [101]. The closest distance between the centroids of two heterocyclic rings was found to be 3.5268 (8) Å.

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.

1,3-Bis(2-methyl-prop-2-eno-yl)-1H-benz-imidazol-2(3H)-one.

Project description:The mol-ecules of the title compound, C15H14N2O3, possesses crystallographically imposed twofold rotational symmetry, so the asymmetric unit contains one half-mol-ecule. The fused-ring system deviates significantly from planarity; the planes of the five- and six-membered rings are twisted with respect to each other by 3.0 (1)°. In the crystal, weak C-H⋯O hydrogen bonds link mol-ecules related by translation in [010] into chains.
