The structures of LaNi 52x Al x D y (x ΒΌ 0:75; 0:25; y ΒΌ 1:01; 1.10, 1.91 and 3.1) were systematically investigated by neutron and X-ray diffraction. D atoms are found to enter the 6m site of the a-phase but not the reported 12n site, while the 6m and 12n sites of the b-phase. In the case of LaNi 4.
