A) The Mayer M-S bond order (solid black circle) and its σ- and π-components (in red and blue colors, respectively) and the bond order between the ML⁺ and SC₆F₅⁻ fragments (solid black squares) in the [ML(SC₆F₅)] complexes. B) The charge donation from the SC₆F₅⁻ ligand to the ML⁺ fragment. C) The ionic component of the ML⁺- SC₆F₅⁻ bonding energy, E_ionic, and the difference, E_int – E_ionic.
