2-Benzoyl-1-(2,4-dichlorophenyl)-3-phenylguanidine

In the title compound, C20H15Cl2N3O, a typical polysubstituted guanidine with normal geometric parameters, the torsion angles [C—N—C—O = 3.8 (2), N—C—N—C = −6.1 (2)°] indicate that the guanidine and carbonyl groups are almost coplanar, due to the pseudo-hexagonal ring formed by intramolecular N—H...O hydrogen bonds. The crystal packing is stabilized by intermolecular N—H...O hydrogen bonds, which link the molecules into centrosymmetric dimers.
