Crystal structure of 5,5'-[(4-fluoro-phen-yl)methyl-ene]bis-[6-amino-1,3-di-methyl-pyrimidine-2,4(1H,3H)-dione].

ABSTRACT: In the title mol-ecule, C19H21FN6O4, the dihedral angles between the benzene ring and essentially planar pyrimidine rings [maximum deviations of 0.036 (2) and 0.056 (2) Å] are 73.32 (7) and 63.81 (8)°. The dihedral angle between the mean planes of the pyrimidine rings is 61.43 (6)°. In the crystal, N-H⋯O hydrogen bonds link mol-ecules, forming a two-dimensional network parallel to (001) and in combination with weak C-H⋯O hydrogen bonds, a three-dimensional network is formed. Weak C-H⋯π inter-actions and π-π inter-actions, with a centroid-centroid distance of 3.599 (2) Å are also observed.
