A neutron diffraction analysis at room temperature of ZrV 2 D 4·5 has been made. The deuterium atoms are found to occupy two types of tetrahedral interstices in the metal atom host structure. One is formed by 1 Zr and 3 V atoms and has an occupancy of 39%, whereas the other one is formed by 2 Zr and 2 V atoms, having an occupancy of 25%. Together these interstices can be considered as forming a three-dimensional infinite network of diffusion paths which is similar to that observed in the deuterated hexagonal Laves-phase ZrMn 2 D 3 . The adjacent D atom sites in this network are about 1.3 aA apart and the average Zr-D and V-D distances are 2.10 and 1.77 aA, respectively. |
