Figure 2
The crystal packing in (I), viewed approximately along the a axis, showing the co-operative association of the molecules, forming chains via C—H⋯π interactions (dashed lines). Cg1 is the centroid of the C5–C10 ring. The atoms labeled with an asterisk (*) or a hash (#) are at the symmetry positions (1 − x, − + y, 1 − z) and (x, −y + , z), respectively. Color key: C, black, H white, Cl green, O red. |
