Abstract

The recent report of the gas-phase loss of nitrogen from [Pt(dien)N3]+ (dien = diethylenetriamine = N-(2-aminoethyl)ethane-1,2-diamine) under collision-induced dissociation (CID) conditions has prompted us to investigate the intriguing structure(s) of [Pt(dien)N]+. This was carried out via CID and ion-molecule reactions (IMR) of [Pt(dien)N]+ in the gas phase. Labelling studies (15N and 2H labelling of the dien ligand) were also employed. As a result, some of the previously proposed structures were ruled out and three other potential structures of [Pt(dien)N]+ are considered. Labelling studies also indicate that the hydrogen atoms of both the amino groups and the carbon backbone of the dien l..
