The isonido cluster [1-PPh3-1,3-(mu-dppm)}-isonido-1,2-RhSB9H8] reacts with [RhCl(PPh3)(3)] to afford the icosahedral cluster [2-PPh3-2,3-Cl-2-2,3-(mu-Cl)-3,7-(mu-dppm)-closo-2,3,1-Rh2SB9H8] in a reaction wherein the metal reagent inserts into the quadrilateral face of the isonido 11-vertex cluster. The structure of the product is explained in terms of a diamond-square-diamond rearrangement and ligand exchange which follows insertion.
