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

ABSTRACT: In the title compound, C(20)H(18)Cl(2)N(4)O(8), 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, inter-molecular C-H?N hydrogen bonds link neighbouring mol-ecules into a ribbon-like structure along the b axis. The ribbons are inter-connected into a two-dimensional network parallel to the bc plane by short inter-molecular Cl?Cl [3.4427?(6)?Å] and Cl?O [3.1420?(9) and 3.1750?(11)?Å] inter-actions. The crystal structure is further stabilized by inter-molecular ?-? inter-actions [centroid-centroid distance 3.4552?(8)?Å] involving the pyrimidine rings.
