(Z)-4-Chloro-N-(1-{2-[3-(4-chloro­benzoyl)ureido]eth­yl}imidazolidin-2-yl­idene)benzamide

The title compound, C(20)H(19)Cl(2)N(5)O(2)S, was obtained from the reaction of 4-chloro­benzoyl isothio­cyanate with diethyl­ene­triamine. The imidazolidine ring is slightly twisted with an N—C—C—N torsion angle of 15.4 (4)°, while the thio­urea moiety maintains its trans–cis geometry. The mol­ecule is stabilized by intramolecular N—H⋯O hydrogen bonds. The crystal structure features N—H⋯O, N—H⋯S and C—H⋯O hydrogen bonds and π–π interactions between benzene rings with a centroid–centroid distance of 3.607 (3) Å.
