Abstract

The synthesis and X-ray crystal structure determination of [(2,3-Et<sub>2</sub>C<sub>2</sub>B<sub>4</sub>H<sub>4</sub>)Co(2,3-Et<sub>2</sub>C<sub>2</sub>B<sub>3</sub>H<sub>3</sub>-5-Bu)Ru]<sub>4</sub> (<strong>3</strong>) are reported. Complex <strong>3</strong> was obtained serendipitously in low yield from a reaction of [(η<sup>4</sup>-C<sub>8</sub>H<sub>12</sub>)Ru(MeCN)<sub>4</sub>][PF<sub>6</sub>]<sub>2</sub> with the (Et<sub>2</sub>C<sub>2</sub>B<sub>4</sub>H<sub>4</sub>)Co(Et<sub>2</sub>C<sub>2</sub>B<sub>3</sub>H<sub>3</sub>Bu)<sup>2-</sup> anion in THF solution at room temperature. The molecular geometry of <strong>3</strong>, isolated as a yellow-orange crystalline solid, is without precedent in boron cluster chemistry and consists of an array of four (Et<sub>2</sub>C<sub>2</sub>B<sub>4</sub>H<sub>4</sub>)Co(Et<sub>2</sub>C<sub>2</sub>B<sub>3</sub>H<sub>3</sub>Bu)Ru units linked <i>via</i> intercluster Ru-B covalent bonds. Each cluster moiety contains a double-decker (C<sub>2</sub>B<sub>4</sub>)Co(C<sub>2</sub>B<sub>3</sub>) sandwich with an exo-polyhedral ruthenium atom occupying a "wedging" position in which it is bound to the C<sub>2</sub>B<sub>3</sub> and the C<sub>2</sub>B<sub>4</sub> ligands as well as to a neighboring sandwich unit. <p>
