2-(Anthracen-9-yl)-10-meth­oxy­benzo[h]quinoline acetone hemisolvate

The asymmetric unit of the title structure, C₂₈H₁₉NO·0.5C₃H₆O, comprises one 2-(anthracen-9-yl)-10-meth­oxy­benzo[h]­quinoline mol­ecule and an acteone mol­ecule with an occupany of 0.5. The solvent mol­ecule is disordered around a centre of symmetry. Its occupancy was determined from NMR data and kept fixed during the refinement. The two conjugated ring systems of the mol­ecule are almost perpendicular to each other; the inter­planar angle between the anthracene and quinoline ring systems is 84.9 (2)°.
