Zusammenfassung
Chloride abstraction from [{M(η3 C3H5)Cl}n] (M Pt, n = 4 or M Pd, n = 2) by (NBu4)2[cis-Pt(C6F5)2(CCSiMe3)2] (1) gives rise to novel homo- and hetero-dinuclear zwitterionic derivatives (NBu4) [{cis-Pt(C6F5)2(CCSiMe3)2}M(η3-C3H5)] (M Pt 2; M Pd 3) which are formed by a M(η3-allyl)+ unit attached to both alkynyl ligands of the {cis-Pt(C6F5)2(CCSiMe3)2}2- fragment. The structure of 3 has been established by X-ray diffraction. © 1994.
