The title compound, [3,3-(PPh(3))(2)-3-Cl-3,1,2-RhC2B9H11] or [RhCl(C2
H11B9)(C18H15P)(2)].1.1CH(2)Cl(2), contains a triangulated icosahedral
closo-RhC2B9 cage. Principal bond distances are Rh-Cl 2.423(2), Rh-P
2.373(2) and 2.383(2), Rh-C 2.190(6) and 2.191(6), and Rh-B 2.203(8)-2
.289(8) Angstrom. The conformation of the Rh(PPh(3))(2)Cl group above
the C2B3 face of the dicarbaborane ligand is such that the Rh-Cl bond
is located above the cage C-C vector.
