3,3'-Bis(3,4,5-trimethoxy-benzo-yl)-1,1'-(o-phenyl-ene)dithio-urea ethanol solvate.

In the mol-ecule of the title compound, C(28)H(30)N(4)O(8)S(2)·C(2)H(6)O, the benzene ring is oriented at dihedral angles of 38.50 (6) and 5.68 (5)° with respect to the trimethoxy-phenyl rings, while the two trimethoxy-phenyl rings are oriented at a dihedral angle of 44.18 (5)°. Intra-molecular N-H⋯O and N-H⋯S hydrogen bonds result in the formation of non-planar six-, seven- and eight-membered rings. The twisting modes of the two side arms are different [C-N-C-O and C-N-C-N torsion angles = 0.1 (3) and 11.8 (3)°, respectively, in one arm, and 4.6 (3) and -11.5 (3)° in the other]. In the crystal structure, inter-molecular N-H⋯O and O-H⋯O hydrogen bonds link the mol-ecules.
