The structure of Li3AlD6

The structure of Li3AlD6 has been determined by combined synchrotron X-ray and neutron diffraction. The space group is R3 with unit-cell dimensions a = 8.07117(10) and c = 9.5130(2) A. The structure consists of isolated and close to regular AlD63- octahedra, which are connected via six-coordinated L...

Zusammenfassung:	The structure of Li3AlD6 has been determined by combined synchrotron X-ray and neutron diffraction. The space group is R3 with unit-cell dimensions a = 8.07117(10) and c = 9.5130(2) A. The structure consists of isolated and close to regular AlD63- octahedra, which are connected via six-coordinated Li. The Al-D distances are 1.734-1.754 A, and the Li-D distances are 1.892-2.120 A. The shortest D-D distance of 2.395 A is found within the octahedra. The structure can be described as a distorted bcc structure of AlD63- units with all tetrahedral sites filled with Li.
