π-Stacking of the two unique molecules of (2) showing the C—H⋯π and π–π interactions as grey dashed lines. Part (a) shows the C1–C14 anthraquinone unit and (b) the C19–C32 anthraquinone unit. Displacement ellipsoids drawn at the 50% probability level [symmetry codes: (#1) x − 1, y z; (#2) 3 − x, 1 − y, 1 − z; (#3) 2 − x, 1 − y, 1 − z; (#4) 1 + x, y, z]. |
