摘要：

In the title compound, C25H14F3N3O3, the dihedral angle between the planes of the benz[4,5] imidazo[1,2-a] pyrimidine unit (r.m.s. deviation = 0.035 angstrom) and the benzochromene ring system (r.m.s. deviation = 0.106 angstrom) is 72.82 (5)degrees. In the crystal, molecules are linked by C-H center dot center dot center dot O interactions, generating [010] C(9) chains. A weak aromatic pi-pi stacking interaction [centroid-centroid separation = 3.5376 (15) angstrom] is also observed.
