o). Evans method magnetic susceptibility data indicate that 3 and 4 contain two unpaired electrons in the ground electronic configuration. Resonance Raman spectra of 3, 4, 5(+), and 6(+) suggest that WRu bonds are 5-10% stronger than corresponding MoOs species. Structural characterization of 5(+) and 6(+) demonstrates metal-metal bond lengths of 2.30 (WRu) and 2.24 (MoOs) Å, respectively. The possibility
