Figure 1
The mol­ecular structure of (I)[link], showing the atom-labelling scheme and the offset ππ inter­action. Displacement ellipsoids are drawn at the 50% probability level and H atoms are shown as small spheres of arbitrary radius. The dashed line indicates the inter­action between the benzene ring centroids Cg1 (C4—C9) and Cg2 (C17—C22).
