Methyl (E)-2-[(3-chloro-4-cyano­phenyl)­imino]-4-(4-chloro­phen­yl)-6-methyl-1,2,3,4-tetra­hydro­pyrimidine-5-carboxyl­ate

In the title compound, C(20)H(16)Cl(2)N(4)O(2), the dihedral angles between the planes of the chloro­phenyl, chloro­cyano­phenyl­imine and ester groups and the plane of the six-membered tetra­hydro­pyrimidine ring are 86.9 (2), 72.6 (2) and 7.9 (2)°, respectively. The Cl atom substituent on the cyano­phenyl ring is disordered over two rotationally related sites [occupancy factors 0.887 (2):0.113 (2)], while the mol­ecular conformation is stabilized by the presence of an intra­molecular aromatic C—H⋯π inter­action. Both N—H groups participate in separate inter­molecular hydrogen-bonding associations with centrosymmetric cyclic motifs [graph sets R (2) (2)(8) and R (2) (2)(12)], resulting in ribbons parallel to [010]. Further weak C—H⋯O hydrogen bonds link these ribbons into a two-dimensional mol­ecular assembly.
