Do agostic interactions play a role in the stabilization of the nido structure of [(PPh3)2RhSB9H10]?

Density functional calculations on [(PPh3)2-nido-RhSB9H10] do not support the proposition that there are agostic interactions between two ortho-phenyl hydrogen atoms and the metal centre. Thus, the claim that these interactions supply the electron-pair ‘missing’ from the formal Wadian electron-count of 13 skeletal-electron-pairs required for a nido 11-vertex cluster is also not supported.
