Methyl 2,6-bis[(5-chloro-4,6-dimethoxypyrimidin-2-yl)oxy]benzoate

Abstract

In the title compound, C20H18Cl2N4O8, the two pyrimidine rings are inclined at dihedral angles of 66.68 (5) and 71.91 (6)° with respect to the central benzene ring. In the crystal structure, intermolecular C—H...N hydrogen bonds link neighbouring molecules into a ribbon-like structure along the b axis. The ribbons are interconnected into a two-dimensional network parallel to the bc plane by short intermolecular Cl...Cl [3.4427 (6) Å] and Cl...O [3.1420 (9) and 3.1750 (11) Å] interactions. The crystal structure is further stabilized by intermolecular π–π interactions [centroid–centroid distance 3.4552 (8) Å] involving the pyrimidine rings.
