Gas-phase fragmentation of single heteroatom-incorporated Co₅MS₈(PEt₃)₆⁺ (M = Mn, Fe, Co, Ni) nanoclusters.

ABSTRACT: Functionalization of metal-chalcogenide clusters by either replacing core atoms or by tuning the ligand is a powerful technique to tailor their properties. Central to this approach is understanding the competition between the strength of the metal-ligand and metal-metal interactions. Here, using collision-induced dissociation of atomically precise metal sulfide nanoclusters, Co₅MS₈L₆⁺ (L = PEt₃, M = Mn, Fe, Co, Ni) and Co_5-xFe_xS₈L₆⁺ (x = 1-3), we study the effect of a heteroatom incorporation on the core-ligand interactions and relative stability towards fragmentation. Sequential ligand loss is the dominant dissociation pathway that competes with ligand sulfide (LS) loss. Because t
