摘要：

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) Angstrom. 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 Angstrom, and the Li-D distances are 1.892-2.120 Angstrom. The shortest D-D distance of 2.395 Angstrom 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. (C) 2002 Elsevier Science B.V. All rights reserved.
