According to recent research published in the journal Inorganic Chemistry, "Stability and coordination of neptunyl(VI) and -(V) acetate complexes in aqueous solution were studied by using UV-vis-near-IR (NIR) and X-ray absorption fine structure (XAFS) spectroscopy. In the neptunyl(VI) acetate system, the formation of (NPO2)-O-VI(AcO)(+), (NPO2)-O-VI(ACO)(2)(aq), and (NPO2)-O-VI(ACO)(3)(-) was detected."
"Both spectroscopic methods provided similar stability constants: log K-1 = 2.98 +/- 0.01, log beta(2) = 4.60 +/- 0.01, and log beta(3) = 6.34 +/- 0.01 from UV-vis-NIR and log K-1 = 2.87 +/- 0.03, log beta(2) = 4.20 +/- 0.06, and log beta(3) = 6.00 +/- 0.01 from ...
