Tris[3,5-bis­(trifluoro­meth­yl)phen­yl]phosphine oxide

In the title compound, C(24)H(9)F(18)OP, an intra­molecular C—H⋯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)°. Each of the six trifluoro­methyl substituents shows rotational disor...

Sumario:In the title compound, C(24)H(9)F(18)OP, an intra­molecular C—H⋯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)°. 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⋯O and C—H⋯F inter­actions.
