Abstract
In the title compound (1), C9H27B10P, the methyl and diisopropylphosph ine groups are bonded to the C atoms of the 1,2-dicarbaborane cage. Bo nd lengths in (1) are P-C(cage) 1.876(6)Angstrom and C(cage)-C(cage) 1 .731(9)Angstrom. In the 1,2-bis(diisopropylphosphine)-substituted carb orane (2), C14H38B10P2, the P-C(cage) distances are 1.894(3) and 1.891 (3)Angstrom, and the C(cage)-(cage) distance is 1.719(3) Angstrom. 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(ca ge)-C(cage) angles.
