The rigid-bond condition for harmonic thermal parameters states that the difference of the mean-square displacements of atoms A and B along the covalent bond A-B is negligible. In this paper, the corresponding condition for non-bonded intramolecular

A neutron diffraction study of ZrMn2D3 at room temperature shows that the deuterium atoms occupy tetrahedral interstices which are formed by two Zr and two Mn atoms. The interstices are partially occupied and represent a 3-dimensional infinite networ

X-ray and neutron diffraction experiments performed on Mg2Ni(H,D)x (0 ⩽ x ⩽ 3.9) confirmed the existence of a structural phase transformation at about 235 °C. The high temperature phase (a = 6.49 A, space group Fm3m) has an antifluorite-type met

The deuterated C15-type Laves phase ZrV2D3.6 undergoes a structural phase transition near room temperature (T ≈ 325 K). In the cubic high-temperature phase the deuterium atoms are disordered over two types of tetrahedral interstices, the centres of

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

The presence of temperature dependent superstructure lines in the neutron diffraction pattern of LaD 3 suggests the occurence of a low temperature phase transformation. It is of second order and probably due to an ordering of the D atoms on off-centr

The distribution of the deuterium atoms in the deuterated Laves-phase ZrV 2 D x was measured by neutron powder diffraction for deuterium concentrations x of 1.5, 2.8 and 4.9. At low deuterium concentrations only the tetrahedral interstices formed by

Single-crystal neutron diffraction data have been used to examine the distribution of mobile Ag+ ions in anion-ordered β-Ag3SI (space group Pm3m) and anion-disordered α-Ag3SI (space group Im3m) at 8 temperatures in the overall range 23° to 475°C.
