Abstract

Electron paramagnetic resonance, electronic absorption, and resonance Raman spectroscopy reveal that in the oxalate-bridged compounds, [[(tBuCO2)3M2]2(μ-O2CCO2)]+[PF6]−, the unpaired electron is delocalized over four metal centers (M = Mo or W) as a result of M2 δ to bridge π conjugation, but in the related cationic perfluoroterephthalate-bridged species, the tungsten complex is delocalized and the molybdenum analogue valence trapped.
