1-Diphenylphosphino-2-phenyl-1,2-dicarba-closo-dodecaborane(12)

The two crystallographically independent molecules of the title compound, 1-[(C6H5)2P]-2-C6H5-1,2-C2B10H10 (C20H25B10P), in the asymmetric fraction of the unit cell are highly congruent. The conformation of the cage phenyl groups is defined by θ=1.15° and the average C1-C2 distance is 1.744(8)A, which is significantly longer than that usually found for 1,2-C2B10H10 compounds. The PPh2 substituent is tilted away from an idealized radical position on C1 as a result of intramolecular crowding.
