Abstract/Summary

Reaction of Ru(III)(L)(dmf)Cl-3 (1) (L = 4,4,4',4'-tetramethyl-2,2'- bisoxazoline, dmf = N,N-dimethylformamide) with an excess of sodium azide in a methanol-water mixture leads to the isolation of the sodium salt of a Ru( VI) nitrido complex of the tetraanion of N,N'-bis-(2,2-dimethyl-1-hydroxyethyl)-1,2-ethanediamide ( L'H-4; H a dissociable proton) of the formulation Na[Ru(L')(N)(H2O)].1.4H(2)O (2). Complex 2 is not generated in the absence of light. A tentative mechanism for the reaction is proposed and a Ru(IV) intermediate, Na[Ru(L')(N-3)(H2O)] . 2CH(3)OH.2H(2)O (3), isolated.
