There are two crystallographically independent mol-ecules in the asymmetric unit of the title heteroaryl chalcone, C(21)H(14)OS: the dihedral angle between the thio-phene and anthracene rings is 75.07 (17)° in one mol-ecule and 76.32 (17)° in the other. The crystal structure is consolidated by 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 inter-actions [Cg⋯Cg = 3.745 (3) Å].
在标题杂芳基查尔酮C₂₁H₁₄OS的不对称单元中有两个晶体学独立分子：在一个分子中噻吩环与蒽环之间的二面角为75.07 (17)°，在另一个分子中为76.32 (17)°。晶体结构通过短的C⋯O [3.348 (5)-3.394 (5) Å]、C⋯S [3.607 (5)-3.666 (5) Å]和S⋯O [2.926 (3) Å]接触，以及C-H⋯π和π-π相互作用 [Cg⋯Cg = 3.745 (3) Å]得以巩固。
