Abstract top

The title compound, C19H21ClN6O4, is a 1:2 adduct of p-chlorobenzaldehyde and uracil. It crystallizes with two molecules in the asymmetric unit. The two uracil units in the same molecule are connected by a pair of strong N-H...O hydrogen bonds. The packing is stabilized by N-H...O, C-H...O and C-H...N interactions.

Comment top

Heterocyclic compounds, especially six-membered pyrimidine ring and their derivatives have occupied an important place among organic compounds owing to their various biological signifiances (Zheng et al., 2007). They have been explored for the development of various pharmaceutically important compounds because of their medicinal values (Jain et al., 2006). They also form the basic structural fragment of many alkaloids and pharmacologically active compounds. As part of our ongoing programme on bioactive pyrimidine molecules, we have synthesized a new pyrimidine compound starting from an important building block namely 6-Amino- 1,3-dimethylpyrimidine-2,4(1H, 3H)-dione (Blicke & Godt, 1954; Das et al., 2008). The title compound crystallizes with two molecules in the asymmetric unit. The two uracil moieties in the same molecule are connected by a pair of strong N—H···O hydrogen bonds. The packing is stabilized by N—H···.O, C—H···.O and C—H···.N interactions.

Related literature top

For the biological activity and medicinal applications of heterocyclic compounds, especially pyrimidine derivatives, see: Zheng et al. (2007); Jain et al. (2006). The title compound was synthesized from 6-amino- 1,3-dimethylpyrimidine-2,4(1H, 3H)-dione, which is an important building block, see: Blicke & Godt (1954); Das et al. (2008)

Experimental top

Distilled water was added in excess to 6-Amino-1,3-dimethylpyrimidine-2,4(1H,3H) -dione (2 mmol) in order to dissolve it completely in a stirring condition. Then, p-chlorobenzaldehyde was added until a precipitate appeared. After 1 hr of stirring the product was filtered and purified by column chromatography. The product was recrystallized by using distilled ethanol, yielding suitable crystals for data collection.

Refinement top

All hydrogen atoms were found in difference Fourier maps. They were refined using a riding model with N-H = 0.86 Å, Caromatic-H = 0.93 Å, Cmethyl-H = 0.96 Å, Ctertiary-H = 0.98 Å and with U(H) set to 1.2 Ueq(C,N) or 1.5 Ueq(Cmethyl).

Special details top

Geometry. All s.u.'s (except the s.u. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell s.u.'s are taken into account individually in the estimation of s.u.'s in distances, angles and torsion angles; correlations between s.u.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell s.u.'s is used for estimating s.u.'s involving l.s. planes.

Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > 2σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger.
