Sažetak
Metal-metal bonding in the icosahedral metal-rich sulfides of Ta is considered from the point of view of extended Hückel calculations via Mullikan overlap populations and from the point-of-view of Pauling bond order. It is found that the two approaches are generally consistent, but that the overlap populations provide a more sensitive estimate of reaction energies. The results are consistent with a strong stabilization of the icosahedral clusters by central atom to icosahedral metal atom bonding and a weak destabilization (relative to the disproportionation products) by the icosahedral metal atom bonds.
