[(Cp*RuCl)(2)(mu-Cl)(2)]: Bond-stretch or spin-state isomerism?

Broken-symmetry density functional theory shows that there is no intrinsic link between the change in structure and the change in spin state shown by [(Cp*RuCl)2(μCl)2]. The bistability observed in this complex should therefore be regarded as an example of bond-stretch isomerism, rather than spin-st...
