Table 3. π–π interactions (Å,°).
Cg1, Cg2 and Cg3 are as defined in Table 2. CgI⋯CgJ is the distance between ring centroids. The dihedral angle is that between the planes of the rings I and J. CgI Perp is the perpendicular distance of CgI from ring J. CgI Offset is the distance between CgI and the perpendicular projection of CgJ on ring I.
