Synthetic, structural, electrochemical, and theoretical studies of heterometallic aggregates with a [Pt(2)(mu-S)(2)M] core (M = Hg, Au).
Novel electroactive multimetallic compounds based on the [Pt(2)(mu(2)-S)(2)M] core, viz. [Pt(2)(PPh(3))(4)(mu(3)-S)(2)HgFc]PF(6) (1) [Fc = (eta(5)-C(5)H(4))Fe(eta(5)-C(5)H(5))] and [Pt(2)(PPh(3))(4)(mu(3)-S)(2)Hg(2)Fc'](PF(6))(2) (2) [Fc' = Fe(eta(5)-C(5)H(4))(2)], have been synthesized under the guide of electrospray mass spectrometry. The electrochemistry of these ferrocene funtionalized compounds together with the reported [Pt(2)(PPh(3))(4)(mu(3)-S)(2)HgPPh(3)](PF(6))(2) (3), [Pt(2)(PPh(3))(4)(mu(2)-S)(mu(3)-S)HgPh]PF(6) (4), and [Pt(2)(PPh(3))(4)(mu(2)-S)(mu(3)-S)AuPPh(3)]PF(6) (5) have been investigated using cyclic voltammetry and DFT calculations. These results point to a prominent ligand-based oxidation.
