Abstract

Binuclear complexes of platinum(I) [Pt2(C6X5)2L2(PPh 3)2] (X = F, L = CO, p-MeC6H4NC, C6H11NC, or ButNC; X = Cl, L = CO or p-MeC6H4NC) have been prepared by a redox condensation reaction between cis-[Pt(C6X5)2L2] and [Pt(η2-C2H4) (PPh3)2]. The reactivity of these binuclear complexes towards phosphines, isocyanides, Mel, and I2 has been studied. The structure of [Pt2(C6F5)2(CO) 2-(PPh3)2] has been determined by single-crystal X-ray diffraction; space group C2/c, a = 18.272(4), b = 16.006(3), c = 17.787(5) Å, β = 101.046(19)°, Z = 4, R = 0.0378 for 3 449 unique reflections with F ≥ 6σ(F). The structure consists of two Pt(C6F5)(CO)(PPh3) fragments linked by a Pt-Pt bond [2.599(1) Å].
