The anionic mixed-metal cluster [Ru3Ir(CO)13]–1, found to be catalytically active in the carbonylation of methanol, reacts with methanol at 70 °C to give, with O–H activation of the substrate, the cluster anion [HRu3Ir(CO)12(OMe)]–2, which upon prolonged reaction loses formaldehyde to give the cluster anion...

    Summary
    The anionic mixed-metal cluster [Ru3Ir(CO)13]1, found to be catalytically active in the carbonylation of methanol, reacts with methanol at 70 °C to give, with O–H activation of the substrate, the cluster anion [HRu3Ir(CO)12(OMe)]2, which upon prolonged reaction loses formaldehyde to give the cluster anion [H2Ru3Ir(CO)12]3; both anions 2 and 3 crystallise together as the double-salt [N(PPh3)2]2[HRu3Ir(CO)12(OMe)][H2Ru3Ir(CO)12] the single-crystal X-ray structure analysis of which reveals a butterfly Ru3Ir skeleton for 2 and a tetrahedral Ru3Ir skeleton for 3.
