WebX-ray analysis revealed that the two phenanthrene units were closely stacked with strong π–π interactions at the interplanar distance of ~3.5 Å. The strong π–π interactions between phenanthrene units forced the molecule into a bowl-like shape. The maximum interatomic distance of the structure was found to be 1.975 nm between C107 and C106.
