(Z)-3-(9-Anthr­yl)-1-(4-methoxy­phen­yl)prop-2-en-1-one

The title chalcone derivative, C(24)H(18)O(2), which consists of the substituted 4-methoxy­phenyl and anthracene rings bridged by the prop-2-en-1-one unit, exists in a cis configuration. The mol­ecule is twisted, the inter­planar angle between the benzene and anthracene rings being 69.50 (10)°. The meth­oxy group is coplanar with the attached benzene ring [C—O—C—C angle = 2.9 (3)°]. In the crystal structure, mol­ecules are linked into chains along the a axis by a weak C—H⋯O(enone) inter­action. The chains are stacked along the c axis. A C—H⋯π inter­action involving the benzene ring is observed.
