Abstract

The structure of new mixed-valent An(IV)/Np(V) compounds [An(NpO2)(H2O)3(CBr3COO)5]·CBr3COOH·nH2O, where An(IV) = Th and Np, was studied. Two independent Np(V) atoms have the coordination surrounding in the form of pentagonal bipyramids with the O atoms of NpO +2 dioxocations in apical positions; the equatorial planes of the bipyramids are constituted by the O atoms of five CBr3COO− ions. Two independent An(IV) atoms have the oxygen surrounding in the form of distorted tricapped trigonal prisms (CN = 9) constituted by the O atoms of four CBr3COO− ions, two NpO +2 cations, and three water molecules. Eight of ten independent CBr3COO− anions link the An4+ and NpO +2 cations in the bidentate bridging fashion into electrically neutral chains [An(NpO2)(H2O)3(CBr3COO)5]n, and two CBr3COO− anions interact with two independent NpO +2 dioxocations in the monodentate fashion. CBr3COOH and water molecules are located between the layers. In the [An(NpO2)(H2O)3(CBr3COO)5]n chains, NpO +2 cations alternate with An4+ cations, and mixed-valent An(IV)/Np(V) cation-cation interaction arises, in which each NpO +2 cation acts as a bidentate ligand and An4+ acts as coordination center for two dioxocations. [Th(NpO2)(H2O)3(CBr3COO)5]·CBr3COOH·2H2O is the first example of a Th(IV) compound in which cation-cation bonds with the NpO +2 ions are present.
