Description
AmTesub(1.73(2)), tetragonal, P4/nmm, a = 4.358 (1), c = 9.027 (3) A at 296 K, Z = 2, Dsub(c) = 8.99 Mg m-3. Crystals were synthesized from elemental Te and 243Am. The structure is of the anti-Fe2As type and isomorphous with NdTesub(1.8). Layers of Te atoms are interleaved with puckered double layers of composition AmTe. The amount of substoichiometry from AmTe2 was determined, and it was found to result from random vacancies in the pure Te layers. Interatomic distances suggest that the nature of the Am-Te bonds is intermediate between ionic and covalent. (Auth.)
