Abstract

Bond dissociation energies of the metal hydroxide dications of Sc, Fe, and Co have been obtained through charge stripping of ions produced by fast atom bombardment. The reactions for fragmentation of the doubly charged transition metal complexes FeOH2+ and CoOH2+ to produce M+ + OH+ are exothermic by 0.6 ± 0.5 and 2.2 ± 0.5 eV, respectively. For ScOH2+, the corresponding reaction is endothermic by 4.9 ± 0.3 eV. The dissociation reaction to form M2+ and the corresponding neutral ligand is endothermic by 4.7 ± 0.3 eV for ScOH2+, and by 2.5 ± 0.5 and 1.9 ± 0.5 eV for FeOH2+ and CoOH2+, respectively.
