Deskripsi
In the title compound, C20H11Cl2F4N3, the central pyrazolo[1,5-a]pyrimidine unit is almost planar [the mean deviation from the best least-square plane through the nine atoms is 0.006 (2) Å]. The fluorobenzene ring is rotated out of this plane by 10.3 (3)°, whereas the dichlorobenzene ring is rotated by 46.2 (3)°. The crystal packing is dominated by Cl...Cl interactions of 3.475 (3) Å and van der Waals interactions.
