Sodium salt of diethyldithiocarbamate (NaDDC) is one of the best‐known organic reagents which form extractable chelates with many metal ions. Although many data on the characteristics of metal‐DDC complexes have been published, no information about organometal complexes is available. In this work, the calculation of stability constants of trialkyllead‐DDC complexes is described and their values are measured by electrochemical techniques. Obtained values are (1.9 ± 0.7) × 10 6 for (C 2 H 5 ) 3 PbDDC and (3.1 ± 1.5) × 10 5 for (CH 3 ) 3 PbDDC. The application of these constants for the prediction of trialkylleads behavior during complexometric extraction from water to organic solvent is discussed.
