✦ Synopsis
In the laser ablation-molecular beam (LAMB) method, laser ablation of metal substrates in vacuum is utilized for the formation of novel organometallic and metal complex compounds containing monopositive metal ions. Mixed-metal binuclear carbonyl ions [MCr(CO) n ] + , n = 0-6, are prepared in the gas phase by the reaction of laser-ablated metal ions (M + ) and Cr(CO) 6 in the molecular beam injected nearby. The relative abundance of these ions, for M = transition metals, can essentially be explained by the M + -Cr bond dissociation energies. Results of density functional calculation show that this is essentially valid
