195Pt and 1H NMR has been used to show that addition of chlorine and bromine to [Pt(CN)4]2_ in presence of perchloric acid in water results in cyanide and water scrambling with formation of eleven complexes of the type [Pt(CN)4-nCl(H2O)n+1](n-1)+ (n=0, 1, 2, 3, 4). Addition of NBu4OH to this solution gives (NBu4)2[Pt(CN)4Cl(OH)]. NMR measurements in acetone also show cyanide and hydroxyl group scrambling with formation of complexes of the type [Pt(CN)4-nCl(OH)n+1]2-, (n=0, 1, 2, 3, 4).
