Abstract

The paramagnetic cluster anions Cp‘&lt;INF&gt;2&lt;/INF&gt;Mo&lt;INF&gt;2&lt;/INF&gt;Co&lt;INF&gt;2&lt;/INF&gt;S&lt;INF&gt;4&lt;/INF&gt;(CO)&lt;INF&gt;2&lt;/INF&gt;&lt;SUP&gt;-&lt;/SUP&gt; (&lt;BO&gt;6&lt;/BO&gt;), and Cp*&lt;INF&gt;2&lt;/INF&gt;Mo&lt;INF&gt;2&lt;/INF&gt;Co&lt;INF&gt;2&lt;/INF&gt;S&lt;INF&gt;4&lt;/INF&gt;(CO)&lt;INF&gt;2&lt;/INF&gt;&lt;SUP&gt;-&lt;/SUP&gt; (&lt;BO&gt;6*&lt;/BO&gt;) were prepared by the reaction of Cp‘&lt;INF&gt;2&lt;/INF&gt;Mo&lt;INF&gt;2&lt;/INF&gt;Co&lt;INF&gt;2&lt;/INF&gt;S&lt;INF&gt;3&lt;/INF&gt;(CO)&lt;INF&gt;4&lt;/INF&gt; with p-toluene thiolate or by Na amalgam reduction of the cubane Cp*&lt;INF&gt;2&lt;/INF&gt;Mo&lt;INF&gt;2&lt;/INF&gt;Co&lt;INF&gt;2&lt;/INF&gt;S&lt;INF&gt;4&lt;/INF&gt;(CO)&lt;INF&gt;2&lt;/INF&gt; (Cp* = C&lt;INF&gt;5&lt;/INF&gt;Me&lt;INF&gt;4&lt;/INF&gt;Et), respectively. The CO-substituted cluster Cp‘&lt;INF&gt;2&lt;/INF&gt;Mo&lt;INF&gt;2&lt;/INF&gt;Co&lt;INF&gt;2&lt;/INF&gt;S&lt;INF&gt;3&lt;/INF&gt;(CO)&lt;INF&gt;3&lt;/INF&gt;(SAr)&lt;SUP&gt;-&lt;/SUP&gt; (&lt;BO&gt;7&lt;/BO&gt;) was a minor byproduct in the synthesis of &lt;BO&gt;6&lt;/BO&gt;. The X-ray crystal structures of these anionic clusters were determined. The effects of the addition or removal of electron density from the cluster core on the cluster structure is presented.
