Fig. 6: Fragmentation efficiency curves of the ligand and ligand sulfide losses for Co_5-xFexS₈L₆⁺ (x = 1–3).

a Comparison of the fragmentation efficiency curves of the first four ligand losses (1L, 2L, 3L, and 4L), b and the competing LS losses (1L1S, 2L1S, 4L1S, and 4L1S) for Co₅FeS₈L₆⁺, Co₄Fe₂S₈L₆⁺, and Co₃Fe₃S₈L₆⁺.
