Electrospray studies of a water soluble platinum (II) phosphine complex, chlorotris(1,3,5-triaza-7-phosphaadamantane)platinum (II) chloride (TPA)(3)PtCl2

The positive- and negative-ion electrospray spectra of methanolic solutions of a water-soluble platinum (II) phosphine complex, chlorotris(1,3,5-triaz a-7-phosphaadamantane)platinum (II) chloride, have been shown to contain a series of platinum (II) cations and anions, Mono-platinum ions such as [Pt( TPA)(3)CI](+) and [Pt(TPA)(2)Cl-2]Cl- (TPA = 1,3,5-triaza-7-phosphaadamanta ne) were the most abundant ions but poly-platinum ions were also observed, The ions have been subjected to two different dissociation experiments and the results for skimmer and on-resonance collision-induced dissociations co mpared, Substitution reactions such as halide exchange and phosphine exchan ge have been monitored in solution. The gas-phase reactions of hydrogen sul fide with selected ions have been studied.
