Figure 3 A view of the offset face-to-face π-stacking in the structure of title compound, with a solid line indicating one interaction and a dashed line indicating one of the Cl1⋯Cl2 interactions. For symmetry codes: (iii) −x, −y + 1, −z; (iv): −x, −y + 1, −z + 1. Displacement ellipsoids are shown at the 50% probability level. |
