Table 3. π⋯π interactions (Å, °).

π⋯π contacts	Cg⋯Cg(Å)	αa(°)	βb(°)	Cg⋯Plane(Å)
Cg(C1→C6)⋯Cg(C7→C12)iii	3.8221	4.87	27.32	3.616
Cg(C15→C20)⋯Cg(C21→C26)iv	3.8284	5.68	23.57	3.642

Notes: α^a = angle between planes of two aromatic rings. β^b = angle between Cg⋯Cg line and normal to the plane of the first aromatic ring. Symmetry codes: (iii) ; (IV) .
