Uranyl ion was found to form an orange-yellow colored complex with thioma1ic acid. Spectrophotometric measure ments revea1 a composition of 1: 1 as UO/sub 2/(II): TMA in the complex, where TMA stands for thiomalic acid. Thiomalic acid is found to behave as a bidentate ligand with UO/sub 2/(II) in this complex. This was concluded by a potentiometric method. Magnetic susceptibility measurements, however, show an anomalous magnetic behavior. The formation constant log K, nt fixed pH and ionic strength as calculated from the spectrophotometric curves, comes out to be 3.0 plus or minus 0.1 and the corresponding free energy of formation was calculated as -4.2 plus or minus 0.2 at 25 deg C.
