Abstract
The structure of the cage in 1,2-Ph2-3-Cp-3,1,2-RhC2B9H9 is distorted from icosahedral by repulsion between the two phenyl rings, forced to lie nearly coplanar by the presence of the Cp ligand. Thus the C(1) ⋯ C(2) distance is 2.51 Å and B(6) approaches to within 2.92 Å of Rh(3). The nature of the distortion, which engenders the description pseudocloso for the RhC2B9 polyhedron, is discussed in relation to 11B NMR chemical shifts and to recent controversy over iso-closo versus hyper-closo descriptors.
