摘要：
In the title compound, C24H9F18OP, an intramolecular C-H center dot center dot center dot O short contact generates a five-membered ring, producing an S(5) ring motif. The dihedral angles between the benzene rings are 57.68 (10), 77.80 (11) and 79.48 (10)degrees. Each of the six trifluoromethyl substituents shows rotational disorder over two positions with refined site-occupany ratios of 0.64 (3)/0.36 (3), 0.649 (14)/0.351 (14), 0.52 (2)/0.48 (2), 0.545 (16)/0.455 (16), 0.774 (9)/0.226 (9) and 0.63 (5)/0.37 (5). The crystal structure is stabilized by intermolecular C-H center dot center dot center dot O and C-H center dot center dot center dot F interactions.
