Synthesis, crystal structures, and bonding of the molybdenum cubane compounds [Mo(µ-C5H4Pri)(µ3-S)]4n+, where n= 0, 1, and 2

Abstract
The compounds [Mo(η-C5H4Pri)(µ3-S)]4 n+, where n= 0, 1, or 2 have been prepared and X-ray crystal structure determinations whow them to have a cubane structure: the compounds are related by reversible one electron oxidation–reduction reactions and the photoelectrom spectrum for the neutral compound, n= 0, provides a description of the bonding in the cubane system.
