Nitrido compounds, with osmium

Nitric anhydride, 3 78 Nitric oxide [see Nitrogen (II) oxide] Nitrido compounds with osmium, 6 204... 

The chemistry of ruthenium and osmium bears little resemblance to that of iron except in compounds such as sulfideror phosphides, and in complexes with ligands such as CO, PR3, or A5-C5H5. The higher oxidation states, VI and VIII, are much more readily obtained than for iron and there is an extensive and important chemistry of the tetraoxides, M04, oxohalides and oxo anions. There are analogies between the chemistries of Ru, Os and Re especially in oxo, nitrogen and nitrido compounds. 

The electrochemical properties of a number of isostructural rhe-nium(V) oxo, rhenium(V) imido, osmium(VI) nitrido, of formula [M(E)(X)(Y)(Tp )] (Tp = Tp or Tp, E = O, N-tolyl, N X, Y = hydrocarbyl, halide, triflate), have been described. The reactivity of these complexes as inner-sphere oxidants does not correlate with their peak reduction potentials, whereas the ease of the oxidation of these compounds well parallels their reactivity as oxidants.206...
