The mechanism underlying this difference remains unclear. In this work, the complexation of TBP with NpO<sub>2</sub><sup>2+</sup> and NpO<sub>2</sub><sup>+</sup> in organic solutions is detected by spectrophotometric and microcalorimetric titrations and theoretical calculations. NpO<sub>2</sub><sup>2+</sup> can form 1:1 and 1:2 complexes with TBP, and the stability constants decrease with the increase in water content from 0.5% to 1.5%. In contrast, NpO<sub>2</sub><sup>+</sup> can only form a 1:1 complex with TBP at 0.5% water content and no complexation is observed at higher water content. The enthalpies and entropies of the complexation of TBP with NpO<sub>2</sub><sup>2+</sup> and NpO<sub>2</sub><sup>+</sup> at 0.5% water content are obtained by microcalorimetric titrations, indicating the formation of inner-sphere Np(VI)-TBP complex and outer-sphere Np(V)-TBP complex.

The extraction energies for Np(VI) and Np(V) by TBP are positive and negative, respectively, consistent with the extraction behavior of the neptunyl ions by TBP.
