Laser-Ion Beam Photodissociation Studies of Ionic Cluster Fragments of Transition-Metal Carbonyls R. E. Tecklenburg, Jr., and D. H. Russell* Contribution from the Department of Chemistry, Texas A&M University, College Station, Texas 77840. Received March I I, 1987
Abstract: Ionic cluster fragments of the type M,(CO),,+ are studied by laser-ion beam photodissociation. The systems studied include Mn,(CO),+ ( x = 1-2;y = 0-10, derived from Mn2(CO)lo),Fe,(CO),+ (x = 3; y = 5-12, derived from Fe3(C0),2), ~). photodissociation cross sections for each ion and and Co,(CO),+ (x = 2-4; y = 0-12, derived from C O ~ ( C O ) ~Relative upper limits to bond dissociation energies for M-M and M-CO are reported. Average metal-metal bond energies for the Mn2(CO),+ and Co,(CO),+ ions are found to be 514.5
