The crystal structure of γ-AlD3

gamma-AlD3 was synthesized from LiAlD4 and AlCl3 via thermal decomposition of aluminum hydride etherate in presence of excess LiAlD4. gamma-AlD3 was determined by powder neutron diffraction and synchrotron X-ray diffraction to crystallize in the space group Pnnm. The orthorhombic structure has unit-...

Beschreibung
Zusammenfassung:	gamma-AlD3 was synthesized from LiAlD4 and AlCl3 via thermal decomposition of aluminum hydride etherate in presence of excess LiAlD4. gamma-AlD3 was determined by powder neutron diffraction and synchrotron X-ray diffraction to crystallize in the space group Pnnm. The orthorhombic structure has unit-cell dimensions a=7.3360(3)A, b=5.3672(2)A and c=5.7562(1)A, and it consists of both corner- and edge-sharing AlD6 octahedra where each hydrogen is shared between two octahedra. The average Al-D distances in octahedra with edge-sharing is 1.706A and in the octahedra with only corner-sharing 1.719A.
