The reactions of the fluorovinyl-substituted phosphines PPh 2(CF=CF2) and PPh2(CCl=CF2), with K2PtX4 (X = Br, I) have been investigated. The resulting complexes have been characterized by a combination of 19F and 31P{1H} NMR, IR and Raman spectroscopy. The reactions of these phosphines with K2PtBr4 yield the monomeric complexes cis-[PtBr2{PPh2(CF=CF2)}2] (1) and trans-[PtBr2{PPh2(CCl=CF2)} 2] (2), respectively, whilst the reactions with K2PtI 4 yield both the monomeric species trans-[PtI2{PPh 2(CX=CF2)}2], {X = F (3), Cl (4)}, and the dimeric species [PtI(μ-I){PPh2(CX=CF2)}]2, {X = F (5), Cl (6)}. The dimers 5 and 6 represent the first crystallographically characterised platinum(II) iodide-bridged phosphine complexes, and both adopt the symmetric-trans structure.
