Abstract

The two crystallographically independent molecules of the title compound, 1-[(C₆H₅)₂P]-2-C₆H ₅-1,2-C₂B₁₀H₁₀ (C₂₀H₂₅B₁₀P), in the asymmetric fraction of the unit cell are highly congruent. The conformation of the cage phenyl groups is denned by ? = 1.15° and the average C1-C2 distance is 1.744 (8) Å, which is significantly longer than that usually found for 1,2-C₂B₁₀H₁₀ compounds. The PPh₂ substituent is tilted away from an idealized radial position on C1 as a result of intramolecular crowding.
