Comment top

In this paper, we used the Williamson reaction (Dermer, 1934) to form the title compound, (I), which was synthesized by the reaction of eugenol, sodium hydroxide and cyanuric chloride at 278 K. We have previously reported three compounds of this type [Ma et al.(2010a, 2010b and 2010c)]. In (I)(Fig.1), the dihedral angle between the benzene ring C4—C9 and the triazine ring C2N3C3N1C1N2 is 87.56 (4)°. There are no significantly short intermolecular contacts in the crystal lattice.

Experimental top

492 mg eugenol (3 mmol) was dissolved in 1.2 g 10% sodium hydroxide (3 mmol) in a 100 mL round-bottom flask and the water was then removed in vacuo. Added 30 ml acetonitrile into the flask in an ice bath and after stirring 10 min cyanuric chloride (3 mmol) was added and kept stirred for 2 h at 278 K. The reaction mixture was filtered and solvent was evaporated under vacuum to dryness. The solid mass was dissolved in EtOAc, washed with saturated NaHCO3 and brine, dried over anhydrous Na2SO4, concentrated and purified with column chromatography to afford the crude product. White crystals suitable for X-ray analysis were obtained by slow evaporation of a solution of the title compound in n-hexane/ethyl acetate (1:1 V/V) at room temperature.

Refinement top

The atoms C12 and C13 were found to be disordered over two sites, and the ratio of the occupancy factors refined to 0.718 (7):0.282 (7) and 0.718 (7):0.282 (7) for atoms C12: C12' and C13: C13' respectively.The positions of all H atoms were determined geometrically and refined using a riding model with C—H = 0.93–0.97 Å and Uiso(methyl H) = 1.5Ueq(C) and 1.2Ueq for other H atoms.

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