Abstract

The chelate complexes [(p-cym)RuCl(kappa(2)-Ph(2)PCH(2)CH(2)AstBu(2))]PF6 (3), [(arene)RuCl(kappa(2)-Ph2PCH2CH2PR2)]PF6 (4, 7, 8) and [(p-cym)RuCl(kappa(2)-iPr(2)PCH(2)AstBu(2))]PF6 (11) were prepared either from [(arene)RuCl(NCMe)(2)]PF6 (1, 5) or from [(arene)RuCl2](2) (2, 6), in the presence of NH4PF6 or AgPF6. The stepwise reaction of [(p-cym)RuCl2](2) (2) with Ph2PCH2CH2PtBu2 and AgPF6 gave the hetero-tetranuclear compound [{(p-cym)RuAg(mu-Cl)(2)(mu-P-Ru(1),P-Ag(2)-(Ph2PCH2CH2P2)-C-1- tBU(2))}(2)](PF6)(2) (9), thestructure of which was determined by an X-ray crystal structure analysis. The bidentate As,O donor Ph2P(O)CH(2)CH(2)AstBu(2) also reacted with 2, in the presence of AgPF6, to afford the chelate complex [(p-cym)RuCl{kappa(2)(As, O)-Ph2P(O)CH(2)CH(2)AstBu(2)}]PF6 (10), which was also characterized crystallographically.
