Abstract
The recent report of the gas-phase loss of nitrogen from [Pt(dien)N3]+ (dien = diethylenetriamine) under collisioninduced dissociation conditions has prompted us to investigate whether the analogous fragmentation of [Pt(tpy)N3]+ (tpy = 2,2′: 6′,2″-terpyridine) occurs in the gaseous and condensed phase as well as in the solid state. While such a process occurs in the gaseous phase, attempts to fragment [Pt(tpy)N3]+ by refluxing it in MeCN yielded the tetrazolato complex [Pt(tpy)(N4CMe)]+, and solid state thermolysis resulted in decomposition. In order to examine the mode of binding of the tetrazole to platinum, the related complex [Pt(tpy)(N4CPh)]BF4 was synthesized via a similar route. X-ray crystallography revealed that the tetrazolate ligand in this complex binds through the N 2 position. In addition, the gas-phase reactivity of these complexes has been investigated using electrosprayionization tandem mass spectrometry (ESI-MS/MS). [Pt(tpy)N3]+ fragments to form [Pt(tpy)N]+, which readily reacts with alcohols, CH3CN and (CH3)2CO, to form adducts. The [Pt(tpy)N+R′OH]+ adduct ions (R′ = CH3, CH3CH2 and (CH3)2CH) fragment to yield [Pt(tpy)N+H2]+ ions with concomitant oxidation of the alcohols.
