Synthesis of Heteronuclear Pt-Tl Complexes with Donor-Acceptor Bonds - X-Ray Structures of Cis-(Tl(Mu(2)-Oocch3)Pt(Pph(3))(C6F5)(2)) and (Nbu(4))(2)((Pt(C6F5)(3))(2)(Mu(2)-O,Mu(3)-O’cch3)Tl)(2))
Reactions of the anionic platinum complexes (NBu(4))[Pt(PPh(3))(C6F5)(2)(OCOCH3)] (1) and (NBu(4))(2)[Pt(C6F5)(3)(S)] (S = methanol or acetone) with Tl(I) salts afford the heterometallic neutral cis-[(C6F5)(2)(PPh(3))Pt(mu(2)-OOCCH3)Tl] (2) and the dimeric dianionic (NBu(4))(2)[{(C6F5)(3)Pt}(2){mu(2)-O,mu(3)-O’CCH3)Tl}(2)] (3). Both complexes display Pt-Tl bonds with bond lengths of 2.994(1) Angstrom and 2.884(1) Angstrom, respectively, the latter being the shortest Pt-Tl(I) distance reported so far. The structure of both compounds has been established by X-ray studies.
