Deskripsi

In the title molecule, C20H20N2O2, the central pyrimidine ring forms dihedral angles of 71.9 (1) and 69.8 (1)° with the two benzene rings. In the crystal, weak intermolecular C—H...O hydrogen bonds link molecules into centrosymmetric dimers. The crystal packing exhibits also π–π interactions as indicated by short distances of 3.674 (2) Å between the centroids of the pyrimidine rings of neighbouring molecules.
