Radically complex: Well-defined mononuclear RuI and OsI complexes (see scheme) have metalloradical character, as indicated by EPR spectroscopy and DFT calculations. The Ru^I and Os^I metalloradicals exhibit both one-electron and two-electron redox reactivity. The latter process affords unusual imido complexes with substantial radical character on the {ArN} moiety.
