Crystal structure of 5,5′-[(4-fluorophenyl)methylene]bis[6-amino-1,3-dimethylpyrimidine-2,4(1H,3H)-dione]
In the title molecule, C(19)H(21)FN(6)O(4), 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 c...

Sumario: | In the title molecule, C(19)H(21)FN(6)O(4), 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 molecules, 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 interactions and π–π interactions, with a centroid–centroid distance of 3.599 (2) Å are also observed. |
