Popis: In the title compound, C24H24N2O6, the mean planes of the pyran rings (A and B) are inclined to one another by 69.2 (1)°, while the aromatic ring (D) of the chromene ring system makes dihedral angles of 63.42 (11) and 66.81 (12)° with the pyrimidine (C) and benzene (E) rings, respectively. Pyran ring A has an half-chair conformation, while pyran ring B has an envelope conformation, with the spiro C atom as the flap. In the crystal, molecules are linked by C—H...O hydrogen bonds, forming a supramolecular three-dimensional network. There are also a number of C—H...π interactions present.
