(A) Crystal packing showing edge-on view of pyrene stacking. Molecules repeat along the a direction (vertical) with hydrogen bond links, N2gH···O3d. Pairs of hydrogen bonds to ethanol solvent molecules, O3dH···O1e and O1eH···N7g, hold together adjacent columns of the adduct as seen on the left. (B) Stacking of the pyrene moieties in pairs of molecules with a separation of ≈3.55 Å.
