The chelate complexes [( p ‐cym)RuCl(κ 2 ‐Ph 2 PCH 2 CH 2 ‐s t Bu 2 )]PF 6 ( 3 ), [(arene)RuCl(κ 2 ‐Ph 2 PCH 2 CH 2 PR 2 )]PF 6 ( 4 , 7 , 8 ) and [( p ‐cym)RuCl(κ 2 ‐ i Pr 2 PCH 2 As t Bu 2 )]PF 6 ( 11 ) were prepared either from [(arene)RuCl(NCMe) 2 ]PF 6 ( 1 , 5 ) or from [(arene)RuCl 2 ] 2 ( 2 , 6 ), in the presence of NH 4 PF 6 or AgPF 6 . The stepwise reaction of [( p ‐cym)RuCl 2 ] 2 ( 2 ) with Ph 2 P‐CH 2 CH 2 P t Bu 2 and AgPF 6 gave the hetero‐tetranuclear compound [{( p ‐cym)RuAg(μ‐Cl) 2 (μ‐ P 1 Ru , P 2 Ag ‐Ph 2 P 1 CH 2 CH 2 P 2 ‐ t Bu 2 )} 2 ](PF 6 ) 2 ( 9 ), the structure of which was determined by an X‐ray crystal structure analysis. The bidentate As,O donor Ph 2 P(O)CH 2 CH 2 As t Bu 2 also reacted with 2 , in the presence of AgPF 6 , to afford the chelate complex [( p ‐cym)RuCl{κ 2 ( As , O )‐Ph 2 P(O)CH 2 CH 2 As t Bu 2 }]PF 6 ( 10 ), which was also characterized crystallographically.
