Progress in chemistry of neptunium and plutonium coordination compounds

Analytical review of studies of the latest 5-7 years on synthesis, structure and properties of neptunium and plutonium complexes is presented. In particular, processes of cation-cation interaction of actinyl ions, study of neptunium and plutonium coordination compounds in a solid state, complexing of the given elements in aqueous, organic and mixed solvents are considered. It is stressed that search for new ligands with selective effect on separate valence forms of the elements is an actual problem in Np and Pu coordination chemistry, being of scientific and practical interest
