Expanding icosahedral frameworks: structure and bonding of bicapped icosahedral cluster [(Cp*Co) <sub>4</sub> Fe(CO)B <sub>9</sub> H <sub>11</sub> ]
A bicapped icosahedral cluster, [(Cp*Co)<sub>4</sub>Fe(CO)B<sub>9</sub>H<sub>11</sub>] (Cp* = η<sup>5</sup>-C<sub>5</sub>Me<sub>5</sub>; 1), has been synthesized and structurally characterized. Cluster 1 represents the first <i>closo</i>-metallaborane with a bicapped icosahedral geometry that follows the capped skeletal electron counting rule. Furthermore, a bicapped square antiprism cluster, [(Cp*Co)<sub>3</sub>B<sub>7</sub>H<sub>9</sub>] (2), has been isolated, which obeys Wade's skeletal electron pair (SEP) rule.
