Abstract
-
ESR Spectra assigned to the group IB metal clusters and the groups IA-IIA mixed-metal clusters were generated at temperatures close to 4.2 K. A trimer was assigned to silver co-deposited with N{dollar}\sb2{dollar} while the gold spectra could not be definitively assigned. The calculated isotropic spin population implies that the Ag{dollar}\sb3{dollar} molecules have an acute angle geometry with a {dollar}\rm \sp2A\sb1{dollar} ground state geometry. The ESR spectra of the mixed-metal clusters, NaMg, NaCa, NaSr, KMg and KCa generated in Ar matrices, established a {dollar}\sp2\Sigma{dollar} ground state with substantial delocalization of the unpaired electrons over the group IIA atom. This ground state assignment strongly implies chemical bond formation between the two metallic moieties.
