摘要：

In the title compound, C15H9Cl2F3N2O2, the 1,6-dihydropyrano[2,3-c]pyrazole ring system is almost planar, with a maximum deviation of 0.0226 (14) angstrom, and forms a dihedral angle of 69.90 (6)degrees with the benzene ring. In the crystal, molecules are linked into a helical chain along the c axis by C-H center dot center dot center dot O hydrogen bonds.
