The Surface of Inorganic Oxides or Zeolites as a Nonconventional Reaction Medium for the Selective Synthesis of Metal Carbonyl Complexes and Clusters

“…[Os 10 C(CO) 24 ] 2 - and [Os 5 C(CO) 14 ] 2 - . By working at atmospheric pressure and at 275 °C on MgO 400 , H 2 OsCl 6 is easily converted to [Os 10 C(CO) 24 ] 2- under CO + H 2 (equimolar) 95,118 , whereas [Os 3 (CO) 12 ] affords [Os 5 C(CO) 14 ] 2- under CO. ,, Both anionic clusters can be isolated by extraction with [(Ph 3 P) 2 N]Cl dissolved in acetone but in 65% yield only because they are partially retained by the surface of MgO. ,,, …”
