The complex of Prazeodimium with L. Leucine have been isolated on solid state. The complex has the formula H3[Pr(Leu)3(NO3)3]. This complex reveal that L. Leucine acts as a neutral bidentate ligand towards Pr ion at the presence of nitrate ion with utilizing amino nitrogen and carboxyloxygen for bonding.
