Electrospray studies of a water soluble platinum (II) phosphine complex, chlorotris(1,3,5-triaza-7-phosphaadamantane)platinum (II) chloride (TPA) 3 PtCl 2

The positive- and negative-ion electrospray spectra of methanolic solutions of a water-soluble platinum (II) phosphine complex, chlorotris(1,3,5-triaza-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)3Cl]+ and [Pt(TPA)2Cl2]Cl− (TPA = 1,3,5-triaza-7-phosphaadamantane) 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 compared. Substitution reactions such as halide exchange and phosphine exchange have been monitored in solution. The gas-phase reactions of hydrogen sulfide with selected ions have been studied.
