(Received 9 May 2010; accepted 9 June 2010; online 16 June 2010)

The asymmetric unit of the title compound, C₃₀H₃₄N₄O₆, contains two independent molecules. In one independent molecule, the two ethoxycarbonyl groups are each disordered over two conformations with occupancy ratios of 0.586 (2):0.414 (2) and 0.508 (2):0.492 (2). The crystal packing exhibits weak intermolecular C—H⋯O hydrogen bonds.

Comment top

Glycoluril and its derivatives are widely used as building blocks for studies of self-assembly in homogeneous solution (Freeman et al., 1981; Rebek, 2005; Rowan et al., 1999; Wu et al., 2002). As a part of our ongoing investigation into glycoluril derivatives (Wang et al., 2006), here we report the structure of the title compound (I) (Fig. 1).

The asymmetric unit of (I) contains two independent molecules. In one independent molecule, two ethoxy carbonyl groups are disordered over two conformations each with ratios 0.586 (2)/0.414 (2) and 0.508 (2)/0.492 (2), respectively. The crystal packing exhibits weak intermolecular C—H···O hydrogen bonds (Table 1).

Experimental top

The title compound was synthesized according to the reported method (Wang et al.; 2006). Crystals of (I) suitable for X-ray diffraction were grown by slow evaporation of a dichloromethane-methanol (4:1) solution of the title compound under 293 K.

Special details top

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.
