Structural studies of Li5ReO6, Li4NpO5 and Li5NpO6 by neutron and X-ray powder diffraction

“…The tetrahedral holes are partly filled with Li + if compounds such as LinMO6 (n = 4, 5, 6, 7 or 8) adopt this structure. This model was originally proposed by Scholder [2] and has recently been applied by Tr6mel and Hauck [18] to determine the structure of LisSnO6. In 1969 Hauck included Li5ReO6 in a large list of compounds LinMO6 to which this model could be applied.…”

“…The first syntheses of lithium uranates (VI) [1] and other lithium oxometallates [2] provided evidence that it should be possible to synthesize lithium oxometallates with transuranium ions in high oxidation states. Keller and coworkers pioneered the syntheses and structural characterization of alkali metal oxoneptunates, oxoplutonates and oxoamericiates [3,4].…”

“…The synthesis of LisNpOr, reported in 1969 as the first crystalline Np (VII) compound [5], epitomized the potential of actinide oxometallates to display the highest actinide oxidation states. Extensive structural studies had been carried out on lithium oxometallates by this time, almost all by X-ray powder diffraction [2][3][4]6].…”

“…The structure of LisNpO6 was described as "R3?" [5] on the basis of the similarity of its X-ray powder pattern to that of other lithium oxometallates Li, MO6 [2,6]. During the years since the original preparation of LisNpO6, a single-crystal synthesis of LisReO6 and redetermination of its structure was carried out by Betz and Hoppe [7].…”
