Abstract
AbstractThe reaction of the betain‐like compound O2C2(PPh3)2 (1) with [(cod)PtX2] in THF solution gives the salt‐like compounds (HC{PPh3}2)[(η3‐C8H11)PtX2] (3, X = I; 4, X = Cl) in about quantitative yields. The new η3‐bonded C8H11 ligand is the result of a proton transfer from the coordinated cod ligand to 1 with subsequent release of CO2. The X‐ray analysis of 3 shows the presence of two isomers in a 60:40 ratio, which differ in the bonding of the C8H11 ligand. 3 crystallizes in the triclinic space group $\rm P{\bar 1}$ with the unit cell dimensions a = 1091.7(1), b = 1141.5(1), c = 1649.4(2) pm; α = 80.34(1)°, β = 83.62(1)°, γ = 89.03(1)°, V = 2013.7(4)·106 pm3, Z = 2.
