With tert-BuNH2 the imido derivative is produced::OsO4 + Me3CNH2 → OsO3(NCMe3) + H2OSimilarly, with NH3 one obtains the nitrido complex::OsO4 + NH3 + KOH → K[Os(N)O3] + 2 H2OThe [Os(N)O3]− anion is isoelectronic and isostructural with OsO4.
Thus with NH3 one obtains the nitrido-oxide:: OsO4 + NH3 + KOH → K[Os(N)O3] + 2 H2OThe [Os(N)O3]- anion is isoelectronic and isostructural with OsO4.
