(Received 15 October 2013; accepted 17 October 2013; online 23 October 2013)

In the title compound, C21H23N3O7, the pyrimidine­dione ring adopts a screw-boat conformation, whereas the cyclo­hexenone ring adopts an envelope conformation, with the C atom bearing the methyl groups as the flap atom. The dihedral angle between the mean planes of the pyrimidine­dione and cyclo­hexenone rings is 58.78 (2)°. The pyrimidine­dione and cyclo­hexenone rings form dihedral angles of 59.94 (3) and 54.73 (2)°, respectively, with the 4-nitro­phenyl ring. Relatively strong intra­molecular O—H⋯O hydrogen bonds are observed. In the crystal, mol­ecules are linked by C—H⋯O hydrogen bonds, forming a chain along the c-axis direction.

Comment top

Organic compounds containing pyrimidine scaffold as a core unit are important targets and are known to exhibit various biological and pharmaceutical activities (Kappe, 1993; Ibrahim & El-Metwally, 2010). Dihydropyridine derivatives are particularly well known in pharmacology as L-type calcium channel blockers (Campbell et al., 1988; Elinson et al., 2006; Sun et al., 2006).

In the title compound, the bond lengths (Allen et al., 1987) and angles are generally within normal ranges. The pyrimidinedione ring P(N2/C1/N3/C3/C4/C5) and the cyclohexenone ring Q(C10–C15) are not planar with total puckering amplitude Q(T) of 0.0868 (18) Å (for P) and 0.4810 (2) Å (for Q). The pyrimidinedione ring (P) adopts a screw-boat conformation, whereas the cyclohexenone ring (Q) adopts an envelope conformation and atom C13 is described as the flap atom being away from the plane of the ring with deviation 0.334 (2) Å. These conformations can be rationalized by the respective puckering parameters (Cremer & Pople, 1975) ϕ = 248.7 (12)°, θ = 76.6 (12)° (for P) and ϕ = -4.90 (3)°, θ = 115.1 (2)° (for Q). The dihedral angle between the mean palnes of the pyrimidinedione ring P and the cyclohexenone plane Q is 58.78 (2)°. The ring P and the plane Q form dihedral angles of 59.94 (3) and 54.73 (2)°, respectively, with the 4-nitrophenyl ring. The hydroxy and carbonyl oxygen atoms face each other and are oriented to allow for the formation of two intramolecular O—H···O hydrogen bonds (Table 1 and Fig. 2) typical for bisdimedone derivatives (Sughanya & Sureshbabu, 2012).

Experimental top

The title compound was prepared in a single stage (Horning & Horning, 1946; Kaupp et al., 2003). A mixture of 4-nitrobenzaldehyde (1.51 g, 10 mmol), 5,5-dimethylcyclohexane-1,3-dione (1.40 g, 8 mmol), 1,3-dimethyl-2,4,6(1H,3H,5H)pyrimidinetrione (1.56 g, 10 mmol) and 20 ml of ethanol was heated to 70 °C for about 10 minutes. The reaction mixture was allowed to cool to room temperature and the resulting title compound was filtered and dried. The yellow crystal used for data collection was obtained by crystallization from ethanol at room temperature,(m.p. 446 K; yield 3.69 g, 86%).

Refinement top

All hydrogen atoms were identified from difference in electron density peaks and subsequently treated as riding atoms with d(Csp2—H) = 0.93 Å, d(Cmethyl—H) = 0.96 Å, d(Cmethylene—H) = 0.97 Å, d(Cmethine—H) = 0.98 Å, d(O—H) = 0.82 Å, and Uiso(H) = xUeq(C,O), where x = 1.5 for methyl H and 1.2 for all other H atoms.

Geometry. All esds (except the esd in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell esds are taken into account individually in the estimation of esds in distances, angles and torsion angles; correlations between esds in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell esds is used for estimating esds 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 > 2sigma(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.
