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) ?, b = 18.368 (4) ?, c = 15.193.(5) ?; V = 2519 (1) ?3; Z = 4; β = 105.31 (2)°; ρcalcd = 1.101 g/cm3, monoclinic space group P21/n. Mixed alkyl-chloro complexes, [Ru(N)R4-xClx]- (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.
