In the title compound (1), C 9 H 27 B 10 P, the methyl and diisopropylphosphine groups are bonded to the C atoms of the 1,2-dicarbaborane cage. Bond lengths in (1) are P-C(cage) 1.876(6)A and C(cage)-C(cage) 1.731 (9)A. In the 1,2-bis(diisopropylphosphine)-substituted carborane (2), C 14 H 38 B 10 P 2 , the P-C(cage) distances are 1.894(3) and 1.891(3)A, and the C(cage)-C(cage) distance is 1.719 (3)A. In both compounds, the P atoms are shifted from their expected positions towards the other cluster C atom resulting in low values of the P-C(cage)-C(cage) angles.
