Abstract

The formation constants of bismuth(III) methylthiourea complexes in aqueous solution were determined at 298 K and an acidity of 2 M HClO4 using the “ligand-oxidized ligand species” potentiometric method and the methylthiourea (mtu)-symmetric dimethylformamidine disulfide (mFDS) redox pair. The formation function was obtained, and the conditional (β * n ) and true (β n ) formation constants of Bi(mtu) 3+ n (1 ≤ n ≤ 8) were calculated. The value of β1 and the formation of complexes with coordination numbers higher than six was confirmed by spectrophotometry.
