Abstract
A deuteride of composition NbVCoD2.5 has been prepared at high deuterium pressures (up to P D 2 = 0.2 GPa), and the positions of the metal and D atoms in its structure have been determined by x-ray and neutron diffraction techniques. The deuteride has the same structure as NbVCo (hexagonal Laves phase structure), with the V and Co atoms occupying positions 2a and 6h (B site in AB2) at random and the D atoms residing predominantly in positions 24l and 12k, typical of hydrogen in hexagonal Laves phases. This hydrogen distribution is due to the blocking of sites adjacent to those occupied by hydrogen.
