3-(2,4-Dichloro­phen­yl)-2-oxo-1-oxa­spiro­[4.5]dec-3-en-4-yl 4-chloro­benzoate

摘要

In the title spiro­diclofen derivative, C22H17Cl3O4, the cyclo­hexane ring adopts a chair conformation [four C atoms are planar with a mean deviation of 0.018 Å and the two C atoms at the flap positions deviate by 0.613 (4) and −0.668 (5) Å from the plane]. The dihedral angles between the furan ring and the two benzene rings are 55.78 (3) and 49.92 (3)°. Weak inter­molecular C—H⋯Cl inter­actions are observed in the crystal structure.
