. Notes: Cg1, Cg2 and Cg3 are the centroids of the C9/N10/C11–C14, C1–C4/C11/C12 and C5–C8/C13/C14 rings, respectively. Cg⋯Cg is the distance between ring centroids. The dihedral angle is that between the planes of rings Cgi and Cgj. The interplanar distance is the perpendicular distance of Cgi from ring j. The offset is the perpendicular distance of ring i from ring j.
