Figure 2 Extensive π⋯π stacking interaction between DHB and phen, phen and phen. Cg (light green sphere) denotes the centroid of six-membered ring: Cg1 = C39 - C44, Cg2 = N1 / C13 - C16 / C57, Cg3 = N6 / C45 - C49, Cg4 = N3 / C1 - C5. Pink dashed lines show the π - π stacking between ligands [symmetry codes: (i) 1 − x, − y, − z]. |
