(E)-1-(2,5-Dimethyl-3-thien-yl)-3-(2,4,5-trimeth-oxy-phen-yl)prop-2-en-1-one.

ABSTRACT: In the title compound, C(18)H(20)O(4)S, the thio-phene and benzene rings are oriented at a dihedral angle of 10.83?(11)°. The central chain makes dihedral angles of 1.86?(13) and 9.25?(12)° with the benzene and thio-phene rings, respectively. In the crystal, mol-ecules are linked through weak inter-molecular C-H?O inter-actions. ?-? inter-actions are also observed between the benzene rings with a centroid-centroid distance of 3.6832?(12)?Å. The slippage between the benzene rings is 0.956?Å.

In the title compound, C(18)H(20)O(4)S, the thio-phene and benzene rings are oriented at a dihedral angle of 10.83 (11)°. The central chain makes dihedral angles of 1.86 (13) and 9.25 (12)° with the benzene and thio-phene rings, respectively. In the crystal, mol-ecules are linked through weak inter-molecular C-H⋯O inter-actions. π-π inter-actions are also observed between the benzene rings with a centroid-centroid distance of 3.6832 (12) Å. The slippage between the benzene rings is 0.956 Å. ...[more]
