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) Å, and forms a dihedral angle of 69.90 (6)° with the benzene ring. In the crystal, mol­ecules are linked into a helical chain along the c axis by C—H⋯O hydrogen bonds.
