Crystal structure of lutetium aluminate (LUAM), Lu(4)Al(2)O(9)

The crystal structure of the title compound containing lutetium, the last element in the lanthanide series, was determined using a single crystal prepared by heating a pressed pellet of a 2:1 molar ratio mixture of Lu(2)O(3) and Al(2)O(3) powders in an Ar atmosphere at 2173 K for 4 h. Lu(4)Al(2)O(9)...

description The crystal structure of the title compound containing lutetium, the last element in the lanthanide series, was determined using a single crystal prepared by heating a pressed pellet of a 2:1 molar ratio mixture of Lu(2)O(3) and Al(2)O(3) powders in an Ar atmosphere at 2173 K for 4 h. Lu(4)Al(2)O(9) is isostructural with Eu(4)Al(2)O(9) and composed of Al(2)O(7) di­tetra­hedra and Lu-centered six- and sevenfold oxygen polyhedra. The unit-cell volume, 787.3 (3) Å(3), is the smallest among the volumes of the rare-earth (RE) aluminates, RE (4)Al(2)O(9). The crystal studied was refined as a two-component pseudo-merohedric twin.
