Crystal structure of 5-[bis­(4-eth­oxy­phenyl)amino]­thio­phene-2-carbaldehyde

In the title compound, C₂₁H₂₁NO₃S, the planes of the two benzene rings are nearly perpendicular to one another [dihedral angle = 84.50 (10)°] and they are oriented with respect to the plane of the thio­phene ring at dihedral angles of 59.15 (9) and 66.61 (9)°. In the crystal, mol­ecules are linked by weak C—H...O hydrogen bonds, forming supra­molecular chains propagating along the b-axis direction.
