Abstract

Anionic nitridoruthenium(VI) alkyl complexes [Ru(N)Me₄]^- and [Ru(N)(CH₂SiMe₃)₄]^- have been prepared by the alkylation of [Ru(N)(OSiMe₃)₄]^- with AlMe₃ or with Mg(CH₂SiMe₃)₂, respectively. The structure of one of these, [N-n-Bu₄][Ru(N)Me₄], was determined by single-crystal X-ray diffraction: a = 9.359 (3) Å, b = 18.368 (4) Å, c = 15.193 (5) Å; V = 2519 (1) Å ³; Z = 4; β = 105.31 (2)°;ρ_calcd = 1.101 g/cm³, monoclinic space group P2₁/n, Mixed alkyl-chloro complexes, [Ru(N)R4-XclJ^- (R = CH₂SiMe₃, x = 1-2; R = Me, x = 1–3), result from the reaction of HCl(g) with the alkyl complexes. The gold(I) chloro complex Au(PPh₃)Cl reacts in a manner analogous to HCl and converts [Ru(N)Me₄]^- to [Ru(N)ClMe₃]^- with formation of Au(PPh₃)Me. In contrast to the related osmium complexes, both Lewis acid adducts of the ruthenium nitrides and (alkylimido)tetraalkylruthenium complexes are thermally unstable.
