EFFECTS OF METAL-CENTER ORBITAL CONTROL ON CLUSTER CHARACTER AND ELECTRON-DISTRIBUTION BETWEEN BORANE AND HYDROCARBON LIGANDS - SIGNIFICANCE OF THE STRUCTURES OF [MU-9,10-(SME)-8,8-(PPH(3))(2)-NIDO-8,7-IRSB9H9] AND 9,10-(SME)-8-(ETA(4)-C(5)ME(5)H)-NIDO-8,7-RHSB9H9]

Macias et al., EFFECTS OF METAL-CENTER ORBITAL CONTROL ON CLUSTER CHARACTER AND ELECTRON-DISTRIBUTION BETWEEN BORANE AND HYDROCARBON LIGANDS - SIGNIFICANCE OF THE STRUCTURES OF [MU-9,10-(SME)-8,8-(PPH(3))(2)-NIDO-8,7-IRSB9H9] AND 9,10-(SME)-8-(ETA(4)-C(5)ME(5)H)-NIDO-8,7-RHSB9H9], Journal of the Chemical Society.

In 9,10-(SMe)-8-(eta(4)-C(5)Me(5)H)-nido-8,7-RhSB9H9] the non-borane l
igand has been found to prefer {eta(4)-C(5)Me(5)H} rather than {eta(5)
-C(5)Me(5)} character, demonstrating factors behind (a) metallaborane
core cluster control of exopolyhedral ligand-to-metal co-ordination mo
des, and (b) the stability of sixteen-electron transition-element cent
res that engender stable formally 'low' cluster-electron counts.
