title: Crystal structure of 5-[bis-(4-eth-oxy-phenyl)amino]-thio-phene-2-carbaldehyde.
abstract: 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 thio-phene ring at dihedral angles of 59.15 (9) and 66.61 (9)°. In the crystal, mol-ecules are linked by weak C-H⋯O hydrogen bonds, forming supra-molecular chains propagating along the b-axis direction.
