The % contribution of Ecomp (%Ecomp) is calculated through (Ecomp/Estab) × 100 where Estab = Eele + Epol + Edisp.
R = distance between centroids of the interacting molecules in Å.
Cg is the centroid of the n ring formed by the atoms indicated in parenthesis: Cg1 (N11–C15), Cg2 (N27–C26), Cg3 (N29–C33), Cg4 (C5–C10) and Cg5 (C16–C21).
