    Saturated and unsaturated triruthenium clusters containing three sterically demanding phosphine ligands : synthesis and structure of [Ru3(CO)9(PCy3)3] and [Ru3H2(CO)6(PCy3)3]

    In: Journal of the Chemical Society, Dalton Transactions, 1998, p. 515-516

    The reaction of Na[Ru3H(CO)11] with an excess of tricyclohexylphosphine in methanol afforded, depending on the reaction conditions, the tri-substituted clusters [Ru3(CO)9(PCy3)3] (48e) and [Ru3H2(CO)6(PCy3)3] (44e), inaccessible hitherto.

    Carbonate binding to copper(II) in solution: mixed-ligand complex formation and its application to the isolation and separation of the three isomers of [Cu(bpp)(H2O)][ClO4]2 [bpp = 2,6-bis(pyrrolidin-2-yl)pyridine]

    In: Journal of the Chemical Society, Dalton Transactions, 2002, p. 2069-2073

    The binding of the carbonate anion to [Cu(meso-bpp)(H2O)]2+ and rac-[Cu(bpp)(H2O)]2+ [bpp = 2,6-bis(pyrrolidin-2-yl)pyridine] in aqueous solution has been investigated. Formation constants of the carbonato complexes [Cu(meso-bpp)(CO3)] and rac-[Cu(bpp)(CO3)] (1.02 × 103 M–1 and...

    Saturated and unsaturated tetraruthenium clusters containing sterically demanding dicyclohexylphosphido ligands: synthesis and structure of [H4Ru4(CO)8(PCy2)4] and [H5Ru4(CO)8(PCy2)3]

    Süss-Fink, Georg ; Godefroy, Isabelle ; Béguin, Alain ; Rheinwald, Gerd ; Neels, Antonia ; Stoeckli-Evans, Helen

    In: Journal of the Chemical Society, Dalton Transactions, 1998, p. 2211-2214

    The thermal reaction of the dinuclear complex [Ru2(CO)4(O2CH)2(PCy2H)2] with molecular hydrogen in cyclohexane afforded the tetranuclear clusters [H4Ru4(CO)8(PCy2)4] (64e) and [H5Ru4(CO)8(PCy2)3] (62e), both of which have a...
