摘要：

Electron paramagnetic resonance, electronic absorption, and resonance Raman spectroscopy reveal that in the oxalate-bridged compounds, [[((BuCO2)-Bu-t)(3)M-2](2)(mu-O2C-CO2)](+)[PF6](-), the unpaired electron is delocalized over four metal centers (M = Mo or W) as a result of M-2 delta to bridge pi conjugation, but in the related cationic perfluoroterephthalate-bridged species, the tungsten complex is delocalized and the molybdenum analogue valence trapped.
