Several derivatives of the dinuclear complex [Ru(μ‐Cl){κ P, P,Si ‐Si(Me)(C 6 H 4 ‐2‐P i Pr 2 ) 2 }] 2 ( 1 ) are described. The mononuclear cationic arene complex [Ru{κ P, P,Si ‐Si(Me)(C 6 H 4 ‐2‐P i Pr 2 ) 2 }(η 6 ‐C 6 H 6 )](CF 3 SO 3 ) ( 5 ), the phosphane adduct [Ru{κ P, P,Si ‐Si(Me)(C 6 H 4 ‐2‐P i Pr 2 ) 2 }Cl(PPh 3 )] ( 2 ), and the hydride‐bridged dinuclear derivatives [Ru 2 (μ‐Cl)(μ‐H){κ P, P,Si ‐Si(Me)(C 6 H 4 ‐2‐P i Pr 2 ) 2 } 2 ] ( 6 ) and [Ru 2 (μ‐H){κ P, P,Si ‐Si(Me)(C 6 H 4 ‐2‐P i Pr 2 ) 2 }] 2 ( 7 ) retain the fac coordination mode of the κ P, P,Si ligand present in the precursor complex. In contrast, the neutral and cationic acetonitrile derivatives [Ru{κ P, P,Si ‐Si(Me)(C 6 H 4 ‐2‐P i Pr 2 ) 2 }Cl(NCMe) 2 ] ( 3 ) and [Ru{κ P, P,Si ‐Si(Me)(C 6 H 4 ‐2‐P i Pr 2 ) 2 }(NCMe) 3 ](CF 3 SO 3 ) ( 4 ), respectively, show the PSiP pincer coordinated in the more usual mer fashion. Crystal structures determined by X‐ray diffraction are shown for complexes 5 , 6 , and 7 . The factors that influence the choice of coordination mode for the PSiP ligand are discussed.
