摘要：

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 (beta (n) (*) ) and true (beta (n) ) formation constants of Bi(mtu) (n) (3+) (1 a parts per thousand currency sign n a parts per thousand currency sign 8) were calculated. The value of beta(1) and the formation of complexes with coordination numbers higher than six was confirmed by spectrophotometry.
