    “…The second oxidation of the complexes was shown to take place at the metal left unaffected in the first redox step. Finally, the tipping point could be realized in the unlike isomer of the electronically tuned thiophenolate congener [Tp′(CO)(PhS)W{μ‐η(2)‐C,C′‐κ(2)‐S,P‐C(2)(PPh(2))S}Ru(η(5)‐C(5)H(5))‐(PPh(3))], in which valence trapped W(III)/Ru(II) and W(II)/Ru(III) cationic species are at equilibrium.…”

    “…Till now, this simple correlation, basic in the bond valence model (BVM), is widely used in crystal chemistry, but it was considered irrelevant for metalmetal bonds. An extensive analysis of the quantum chemistry data computed in the last years confirms very well the validity of Pauling’s correlation for both localized and delocalized interactions. …”
