In this work, the cation and anion products of the reactions between platinum clusters produced by laser ablation and the benzene molecules seeded in argon have been studied using a high‐resolution reflectron time‐of‐flight mass spectrometer (RTOFMS). The dominant cation products are [C 6n H 6n − k ] + and [Pt m (C 6 H 6 ) n ] + complexes, while the dominant anion products are dehydrogenated species, [C 6 H 5 PtH] − , [PtC 12 H k ] − and [Pt m C 6 H 4 · · · (C 6 H 6 ) n ] − , etc. Some important intermediate structures ([PtC 6 H 6 ] + , [Pt(C 6 H 6 ) 2 ] + , [Pt 2 (C 6 H 6 ) 3 ] + , [C 6 H 5 PtH] − , [Pt 2 C 6 H 4 ] − , [Pt 3 C 6 H 4 ] − and [Pt 4 C 6 H 4 ] − ) have been analyzed using density functional theory (DFT) calculations. Different reaction mechanisms are proposed for platinum cluster cations and anions with benzene, respectively. Copyright © 2006 John Wiley & Sons, Ltd.
