Аннотация: The stability constants of monocomplexes of cysteine (H(2)Cys) and thiosemicarbazide (Tsc) with bismuth(III) at 288, 313 and 333 K in 0.5 M HClO(4) and an ionic strength of 2(NaClO(4)) were determined by spectrophotometry. On the basis of a substantial difference in the stability constants of bismuth monocomplexes with H(2)Cys and Показать полностьюTsc, the high acidity of the investigated solutions, and known coordination modes of these ligands in crystalline compounds, the formation of Bi(HCys-O,S)(2+) and Bi(Tsc-N, S)(3+) is suggested.
