摘要：
Complexation of actinides(VI) (U, Np, Pu) with picolinic acid C 6H5NO2 (HPic) in solution was studied by spectrophotometry. In particular, data on the Np(VI) complexation were obtained for the first time. The complexes [AnO2(HPic)]2+, [AnO2(Pic)]+, [AnO2(Pic)2], and, presumably, [AnO2(HPic)(Pic)]+, and also mixed picolinate-hydroxide complexes can exist in the solution under different conditions. The stability constants of the complexes were estimated. A series of crystalline actinide(VI) picolinate complexes Gu[AnO2(Pic) 3] (An = Np, Pu; Pic is picolinate ion, Gu is guanidinium ion) were synthesized, and their structure was determined. The spectra and thermal behavior of the complexes are discussed. © 2013 Pleiades Publishing, Ltd.
