Fine tuning: A combination of steric and electronic features of bromine-substituted scorpionate ligands and an arene moiety has provided an unexpected μ3-binuclear ionic complex instead of the mononuclear neutral one; this is accounted for by the low thermodynamic stability of the latter species. The coordination chemistry of RuII(arene) toward Tpx ligands was analyzed using X-ray diffraction (see figure), electrochemical and DFT methods.
