N2 - Certain equilibria involving polymeric gold(I) thiomalate complexes have been studied by spectrophotometry and pH measurements in aqueous solution at 25°С and I = 0.2 M (NaCl). Thiomalate protonation constants Hi–1Tm3– + H+ = HiTmi–3 have been found to be logKH1 = 10.23, logKH2 = 4.51, logKH3 = 3.01. Efficient functions have been used to allow for multiple protonation of polymeric complexes Aun Tmm n-3 m Equilibrium constants for reactions Au4Tm4 8− + Tm3– = Au4Tm5 11− (logK45 = 10.1 ± 0.5) and 0.25 Au4Tm4 8− + Tm3– = AuTm2 5− (logK12 = 4.9 ± 0.2) have been determined. Standard potential for AuTm2 5− has been found to be equal to E1/0 0 =–0.260 ± 0.025 V.
