Complexation of oxovanadium(IV) and dioxouranium(VI) with pyrazine-2-carboxylic and pyrazine-2,3-dicarboxylic acids were studied by potentiometric titrn. at 25° and ionic strength 0.5 mol/L (NaClO4). Only mononuclear species occur in the concn. range studied. For both metals, 1:1 and 1:2 (metal:ligand) complexes are formed. A 1:3 complex is formed between oxovanadium(IV) and pyrazine-2-carboxylic acid

Only mononuclear species occur in the concn. range studied. For both metals, 1:1 and 1:2 (metal:ligand) complexes are formed.
