The complexes, trans-Pt(NH3)4 Br22+ and trans-Pt(NH3)4Cl22+ have been electrochemically reduced to Pt(NH3)42+ at a platinum electrode. The electrochemical oxidation of Pt(NH3)42+ at a platinum electrode in aqueous bromide and chloride solutions produced trans-Pt(NH3)4Br22+ and trans-Pt(NH3)4Cl22...detailed
Reduction of trans-[Pt(CN)4Cl2]2− by [Pt(NH3)4]2− and [Pt(en)2]2− was studied at 25°C in the range 0⩽[Cl−]⩽0.4 M by use of stopped-flow spectrophotometry. The stoichiometry [Pt(IV)]:[Pt(II)] is 1:1. Rapid-scan spectra show clear-cut isosbestic points, indicating that no reaction intermediates a...detailed
The redox reaction between [Pt(NH3)4]2+ and [W(CN)8]3− in the presence of Cl− anions in aqueous solution affords single crystals of [PtII(NH3)4]2[WIV(CN)8] and [PtIV(NH3)4Cl2]Cl2. Trapped cyano ligands of [W(CN)8]4− rectangular antiprisms of D2 point symmetry between parallel Pt(II) square plane...detailed
The reaction of dichloride anion radical with tetraammineplatinum(II) ion has been studied in aqueous, acidic solution using the fast-reaction technique of pulse radiolysis in conjunction with UV-visible absorption detection. The second-order rate constant for the reaction of Cl.2 radical with t...detailed
