Abstract

Reversible interconversions between the cluster anions [HRu 3 (CO) 11 ] - and [H 3 Ru 4 (CO) 12 ] - on fully hydroxylated magnesia in the presence of H 2 or CO at a pressure of 1 atm have been observed that mimic interconversions of these ions in basic solution. In the presence of H 2 , the [HRu 3 (CO) 11 ] - anion on fully hydroxylated magnesia is converted to [H 3 Ru 4 (CO) 12 ] - , which in turn transforms back to [HRu3(CO) 11 ] - when H 2 is removed and CO is added. The organometallic species on the fully hydroxylated magnesia surface are mobile at room temperature, and the interconversion steps are reversible and can be repeated. Possible reaction pathways are proposed. & 1997 American Chemical Society.
