Arene and hydride complexes of ruthenium with fac PSiP pincer ligands
Several derivatives of the dinuclear complex [Ru(μ-Cl){κP, P,Si-Si(Me)(C6H4-2-PiPr2)2}]2 (1) are described. The mononuclear cationic arene complex [Ru{κP, P,Si-Si(Me)(C6H4-2-PiPr2)2}(η6-C6H6)](CF3SO3) (5), the phosphane adduct [Ru{κP, P,Si-Si(Me)(C6H4-2-PiPr2)2}Cl(PPh3)] (2), and the hydride-bridged...

| Sumario: | Several derivatives of the dinuclear complex [Ru(μ-Cl){κP, P,Si-Si(Me)(C6H4-2-PiPr2)2}]2 (1) are described. The mononuclear cationic arene complex [Ru{κP, P,Si-Si(Me)(C6H4-2-PiPr2)2}(η6-C6H6)](CF3SO3) (5), the phosphane adduct [Ru{κP, P,Si-Si(Me)(C6H4-2-PiPr2)2}Cl(PPh3)] (2), and the hydride-bridged dinuclear derivatives [Ru2(μ-Cl)(μ-H){κP, P,Si-Si(Me)(C6H4-2-PiPr2)2}2] (6) and [Ru2(μ-H){κP, P,Si-Si(Me)(C6H4-2-PiPr2)2}]2 (7) retain the fac coordination mode of the κP, P,Si ligand present in the precursor complex. In contrast, the neutral and cationic acetonitrile derivatives [Ru{κP, P,Si-Si(Me)(C6H4-2-PiPr2)2}Cl(NCMe)2] (3) and [Ru{κP, P,Si-Si(Me)(C6H4-2-PiPr2)2}(NCMe)3](CF3SO3) (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. |
