Abstract

Reaction of Mo<inf>2</inf>Ir<inf>3</inf>(Î¼-CO)<inf>3</inf>(CO)<inf>6</inf>(Î·5-C<inf>5</inf>H<inf>5</inf>)<inf>2</inf>(Î·5-C<inf>5</inf>Me<inf>5</inf>) with Ir(CO)<inf>2</inf>(Î·5-C<inf>5</inf>Me<inf>4</inf>H) afforded the four-valence-electron-deficient butterfly cluster Ir<inf>4</inf>(CO)<inf>6</inf>(Î·5-C<inf>5</inf>Me<inf>4</inf>H)<inf>2</inf>; its stability has been rationalized with the aid of density functional theory calculations, which suggest that significant additional intracluster bonding alleviates the formal electron deficiency. Reaction of MoIr<inf>4</inf>(CO)<inf>10</inf>(Î·5-C<inf>5</inf>H<inf>5</inf>)(Î·5-C<inf>5</inf>Me<inf>5</inf>) with [N(PPh<inf>3</inf>)<inf>2</inf>][Ir(CO)<inf>4</inf>] afforded the capped octahedral cluster Ir<inf>7</inf>(Î¼<inf>3</inf>-CO)<inf>3</inf>(CO)<inf>12</inf>(Î·5-C<inf>5</inf>Me<inf>5</inf>), which possesses three semi-face-capping CO ligands. These outcomes demonstrate that heterometallic clusters may serve as a potential source of new homometallic clusters following appropriate M-M cleavage.
