New Np(VI) and Pu(VI) pyrazine-2-carboxylates isostructural with the uranyl complex [UO2 · (C4H3N2COO)2(H2O)] · 2H2O were synthesized from aqueous solutions. The unit cell parameters of [NpO2 · (C4H3N2COO)2(H2O)] · 2H2O and [PuO2(C4H3N2COO)2(H2O)] · 2H2O were calculated from the powder X-ray patterns. The thermal behavior of the complexes suggests that the Np(VI) compound contains superstoichiometric water molecules, which are also manifested in the IR spectrum. The absorption spectra of the compounds show that the pyrazinecarboxylic acid anion is a strong complexing agent with respect to Np(VI) and Pu(VI).

The first plutonium(III) borate, Pu2[B12O18(OH)4Br2(H2O)3]·0.5H2O, has been prepared by reacting plutonium(III) with molten boric acid under strictly anaerobic conditions. This compound contains a three-dimensional polyborate network with triangular holes that house the plutonium(III) sites. The plutonium sites in this compound are 9- and 10-coordinate and display atypical geometries.
