1,5-Bis(piperidin-1-yl)-9,10-anthraquinone

In the centrosymmetric title compound, C24H26N2O2, the piperidine ring adopts a chair conformation and is inclined at a dihedral angle of 37.5 (1)°to the anthracene ring system. In the crystal, adjacent molecules are linked through C—H...π and π–π [centroid–centroid distances = 3.806 (1) ] interactions, forming a layer parallel to the bc plane.
