Neutral pentanuclear Pt3Ag2 complexes: crystal structure of trans-[PtCl2{(µ-SC4H8)Pt(C6F5)3(η2-C6H5Me)}2]

Abstract

By treating [NBu₄]₂[trans-PtX₂{(µ-SC₄H₈)Pt(C₆F₅)₃}₂](X = Cl or Br) with AgClO₄(molar ratio 1 :n, where n= 1–4) in dichloromethane–toluene solution the neutral pentametallic complexes trans-[PtX₂{(µ-SC₄H₈)(C₆F₅)₃PtAg(η²-C₆H₅Me)}₂][X = Cl, (1); or Br, (2)] have been obtained. The structure of (1) has been established by X-ray diffraction and shows that two new Pt–Ag bonds have been formed as the result of the addition of two Ag(η²-C₆H₅Me) fragments to the terminal platinum atoms of the trinuclear starting complex.
