title: 1,5-Bis(piperidin-1-yl)-9,10-anthraquin-one.
abstract: 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 mol-ecules are linked through C-H⋯π and π-π [centroid-centroid distances = 3.806 (1) Å] inter-actions, forming a layer parallel to the bc plane.
