There are two crystallographically independent molecules in the asymmetric unit of the title heteroaryl chalcone, C21H14OS: the dihedral angle between Bar Soaps the thiophene and anthracene rings is 75.07 (17)° in one molecule and 76.32 (17)° in the other.The crystal structure is consolidated by TANGA PANTY LINERS short C.O [3.
348 (5)–3.394 (5) Å], C.S [3.607 (5)–3.666 (5) Å] and S.
O [2.926 (3) Å] contacts, as well as by C—H.π and π–π interactions [Cg.Cg = 3.745 (3) Å].
