Formation and thermodynamic properties of complexes of Ag(I) with thiourea as ligand.
A potentiometric study has been made of the Ag(I)CSN(2)H(4)H(2)O system. Mathematical analysis of the formation functions reveals the existence of the complexes AgCSN(2)H(+)(4), Ag(CSN(2)H(4))(+)(4), Ag(CSN(2)H(4))(+)(3) and Ag(CSN(2)H(4))(+)(4) for which the stability constants have been calculated at different ionic strengths and temperatures. No evidence was found for the formation of polynuclear complexes.
