• W2085730436 abstract "The reaction of [Mo2(μ-C8Me8)(η-C5H5)2] (1) with 1 equiv of [Fe(η-C5H5)2][PF6] in CH2Cl2 gives [Mo2(μ-C8Me8)(η-C5H5)2][PF6] (1+[PF6]-), which reacts with a second 1 equiv of [Fe(η-C5H5)2][PF6] or 1 equiv of the trityl radical, •CPh3, to give [Mo2(μ-C8Me7CH2)(η-C5H5)2]+ (2+); depending on the oxidant the activation of one C−H bond of 1, with the formation of 2+, can occur by an EC or EEC mechanism. Complexes 1 and 1+ constitute the first isolable redox pair to show the structural effects of one-electron oxidation on a metal−alkene bond. An X-ray crystal structure analysis shows that the geometry of 1+ is similar to that of 1 and has approximate Cs symmetry. The Mo−Mo distance in 1+ is consistent with the presence of a MoMo double bond. The C8 chain acts as a double μ-allylidene ligand while binding to Mo(2) as an η-alkene through C(4) and C(5). The Mo−C distances for atoms C(1), C(2), C(3), C(6), C(7), and C(8) of the C8 chain are remarkably similar in 1 and 1+ while the Mo(2)−C(4) and Mo(2)−C(5) distances are significantly increased and the C(4)−C(5) distance is decreased in 1+ compared with that of 1. These observed structural changes are consistent with a model for the bonding in the paramagnetic cation in which the unpaired electron occupies an orbital of a‘‘ symmetry which is largely localized on Mo(2) and involved in π-back-bonding with the alkene function of the C8Me8 ligand in the classic Dewar−Chatt−Duncanson manner. This conclusion is supported by detailed NMR and ESR spectroscopic studies on 1 and 1+ and by EHMO calculations." @default.
