The title compound was synthesized according to the procedure reported by Wu et al. (2002). Colourless blocks of (I) were obtained by slow evaporation of a dichloromethane solution at 283 K.
The methoxy and Br groups are disordered in a 0.847 (4):0.153 (4) ratio and the pendant ethoxy group is disordered over two positions in a 0.531 (14):0.469 (14) ratio. The H atoms were placed at calculated positions (C—H = 0.93–0.97 Å) and treated as riding atoms with Uiso(H) = 1.2Ueq(C) or 1.5Ueq(methyl C).

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. |

Glycoluril has also become an important building block in supramolecular chemistry (Branda et al., 1995; Elemans et al., 1999; Isaac & Witt, 2002). The widespread interest in glycolurils has led to a variety of crystal structures reported for a number of its derivatives. We report here the structure of the title glycoluril derivative, (I) (Fig. 1), which is an important intermediate for the preparation glycoluril receptors (Wu et al., 2002). The bond lengths and angles in (I) present no unusual features and are similar to those found in similar compounds (Cao et al., 2006).
The C3N2O oxadiazinane six-membered ring in (I) displays a normal chair conformation. Weak intermolecular C—H···O hydrogen bonds help to establish the packing (Fig. 2).
