title: (3,4-Dimeth-oxy-phen-yl)[2-(thio-phen-2-ylcarbon-yl)phen-yl]methanone.
abstract: In the title compound, C(20)H(16)O(4)S, the thiophene ring makes dihedral angles of 72.9 (2) and 60.5 (2)°, respectively, with the dimethoxy benzene and phenyl rings. In the crystal, C-H⋯O hydrogen bonds link the mol-ecules into a C(9) chain along the b axis. The S and C atoms of the thio-phene ring are disordered over two sets of sites [site occupancies = 0.675 (3) and 0.325 (3)]. A short inter-molecular S⋯O contact [3.084 (2) Å] is observed in the crystal structure, which also features C-H⋯π inter-actions.
