|Abstract:||In the title compound, C20H18Cl2N 4O8, 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 molecules 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) ] and Cl?O [3.1420 (9) and 3.1750 (11) ] inter-actions. The crystal structure is further stabilized by inter-molecular ?-? inter-actions [centroid-centroid distance 3.4552 (8) ] involving the pyrimidine rings.|
