5,15-Diaza-6,16-dihydroxytetrabenzo[b,e,k,n]perylene

The molecule of the title compound, C₃₄H₁₈N₂O₂, belongs to point group C_i. The area between the two opposing phenyl rings is overcrowded so that each phenyl ring is bent out of the diazaperylene skeleton in such a way that one ring is above and the other is below the molecular plane. Due to the ring strain thus induced, the C-C bonds in the bent phenyl rings are no longer equal. There are intramolecular hydrogen bonds between the OH groups and N atoms, which stabilize the molecule. The molecules are stacked in a herringbone fashion, with an interplanar distance of 3.43 (1) Å along the b axis where there are close interatomic contacts.
