%X The recent report of the gas-phase loss of nitrogen from &#91;Pt(dien)N3&#93;+ (dien = diethylenetriamine) under collisioninduced dissociation conditions has prompted us to investigate whether the analogous fragmentation of &#91;Pt(tpy)N3&#93;+ (tpy = 2,2&#8242;: 6&#8242;,2&Prime;-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 &#91;Pt(tpy)N3&#93;+ by refluxing it in MeCN yielded the tetrazolato complex &#91;Pt(tpy)(N4CMe)&#93;+, and solid state thermolysis resulted in decomposition. In order to examine the mode of binding of the tetrazole to platinum, the related complex &#91;Pt(tpy)(N4CPh)&#93;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). &#91;Pt(tpy)N3&#93;+ fragments to form &#91;Pt(tpy)N&#93;+, which readily reacts with alcohols, CH3CN and (CH3)2CO, to form adducts. The &#91;Pt(tpy)N+R&#8242;OH&#93;+ adduct ions (R&#8242; = CH3, CH3CH2 and (CH3)2CH) fragment to yield &#91;Pt(tpy)N+H2&#93;+ ions with concomitant oxidation of the alcohols.
