N2  - The recent report of the gas-phase loss of nitrogen from [Pt(dien)3]+ (dien = diethylenetriamine = N-(2-amino-ethyl)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&#8211;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 ligand are involved in loss of NH3 from [Pt(dien)N]+. The gas-phase chemistry of [Pt(dien)N-NH3]+, the fragmentation product of [Pt(dien)N]+, was also probed using IMR and CID. The crystal structure of the [Pt(dien)3]+ cation has also been determined.
