摘要：

Electronic absorption spectra of different crystalline Pu(V) compounds in the range 400-1200 nm were recorded. The correlation between the spectra of these compounds and their structure was discussed. The intensities of the absorption bands of solid compounds with the pentagonal bipyramidal surrounding of the Pu atom are similar to those observed in solution, whereas the centrosymmetrical hexagonal-bipyramidal surrounding is characterized by substantially decreased intensity of the absorption bands up to their complete disappearance. Comparison of the optical spectra of Pu(V) compounds with known structure and those of aqueous Pu(V) solution shows that the hydration number of PuO 2 + is 5. © 2007 Pleiades Publishing, Inc.
