Complexation of U(vi) with pyridazine-3-carboxylate (PDZ) and pyrazine-2-carboxylate (PAZ) was studied by spectrophotometry, potentiometry and microcalorimetry in 1.0 mol dm-3 NaClO4. Three complexes, [UO2L]+, UO2L2(aq) and [UO2L3]-, were identified and their stability constants (log β) and the corresponding formation enthalpies were
