Abstract
Highly reactive cations [Pt(η4-C4Me4)(solv)x] 2+ (solv = acetone or nitromethane) can be obtained from [{Pt(η4-C4Me4)Cl2}] by chloride abstraction with AgCF3SO3. The solvento complex [Pt(η4-C4Me4)-(Me2CO) x][CF3SO3]2 reacts with cyclopentadines and with hexamethylbenzene to form the sandwich compounds [Pt(η4-C4Me4)(dienyl)]CF3SO 3 (dienyl = η5C5Me5, η5-C5H4Me or η5-C5H5) and [Pt(η4-C4Me4)(η6-C 6Me6)][CF3SO3] 2·Me2CO. The new compounds are characterised by 1H, 13C and 195Pt NMR spectroscopy and cyclic voltammetry. The structure of the hexamathylbenzene complex, determined by X-ray crystallography, reveals an average Pt-C distance of 2.138 Å for the C4Me4 ligand and 2.351 Å for the C6Me6 ligand indicating a pronounced structural trans effect.
