The title compound was purchased from the Dr. Ehrenstorfer GmbH Company. Slow evaporation of a solution in CH2C12 gave single crystals suitable for X-ray analysis.
All H-atoms were positioned geometrically and refined using a riding model with d(C—H) = 1.00 Å, Uiso = 1.2Ueq(C) for Csp3—H, d(C—H) = 0.99 Å, Uiso = 1.2Ueq(C) for CH2 groups, d(C—H) = 0.98 Å, Uiso = 1.2Ueq(C) for CH3 groups, d(C—H) = 0.95 Å, Uiso = 1.2Ueq(C) for aromatic C—H.
Benzobicyclon is a newly developed compound with potent herbicidal activity against Scirpus juncoides, one of the most troublesome weeds in paddy fields. (Im et al., 2015). However, until now its
has not been reported. In the title compound (Fig. 1), the dihedral angle between the plane of the phenyl and chlorobenzene rings is 19.9 (2)°. All bond lengths and bond angles are normal and comparable to those observed in the crystal structures of similar compounds (Brown et al., 2007; Hou et al., 2010).In the
(Fig. 2), intermolecular C1—H1B···O4 hydrogen bond link adjacent molecules, forming chains along the c-axis direction. These chains are linked by C1—H1C···O4 and C3—H3···O2 hydrogen bonds (Table 1), resulting in two-dimensional networks extending parellel to the (011) plane.For information on the herbicidal properties of the title compound, see: Im et al. (2015). For related crystal structures, see: Brown et al. (2007); Hou et al. (2010).

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. |

Benzobicyclon is a newly developed compound with potent herbicidal activity against Scirpus juncoides, one of the most troublesome weeds in paddy fields. (Im et al., 2015). However, until now its crystal structure has not been reported. In the title compound (Fig. 1), the dihedral angle between the plane of the phenyl and chlorobenzene rings is 19.9 (2)°. All bond lengths and bond angles are normal and comparable to those observed in the crystal structures of similar compounds (Brown et al., 2007; Hou et al., 2010).
In the crystal structure (Fig. 2), intermolecular C1—H1B···O4 hydrogen bond link adjacent molecules, forming chains along the c-axis direction. These chains are linked by C1—H1C···O4 and C3—H3···O2 hydrogen bonds (Table 1), resulting in two-dimensional networks extending parellel to the (011) plane.
