The title compound was prepared according to the literature procedure (Sun et al., 2010). The single-crystal suitable for X-ray structural analysis was obtained by slow evaporation of a solution of the title compound in petroleum ether and ethyl acetate at room temperature.
All H atoms were initially located in a difference Fourier map. The C—H atoms were then constrained to an ideal geometry, with C—H distances of 0.96-98 Å, and Uiso(H) = 1.2-1.5Ueq(C). There is a relatively short H···H contact ca. 1.87Å. This appears to be influenced by the hydrogen bonding.

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. |

1,5-Diazabicyclo compounds are important synthetic targets due to their biological activity (Hutton & Bartlett, 2007, Koptelov et al., 2011) and catalytic activity (Taylor et al., 2010). It was discovered that N-dichloroacetyl-1,5-diazabicyclo compounds act as herbicide safeners and these compounds have drawn widespread attention in agricultural biochemistry (Burton et al., 1994, Hatzios, 2004, Loniovereror, 1993). As a part of our ongoing investigation on the bioactivities of safeners we have determined the crystal structure of the title compound.
The molecular structure of the title compound is shown in Fig. 1. In the crystal, weak interolecular bifurcated (C—H)2···O hydrogen bonds connect molecules into one-dimensional chains along [010]. (Fig. 2).
