Abstract The short range structure of molten ErCl3 at 1053 K was investigated by X-ray diffraction. The nearest neighbour distance of Er3+-Cl- and the coordination number of Cl- around Er3+ were estimated to be 2.63 Å and 5.8 Å, respectively, and the Er3+-Er3+ and Cl--Cl- distances 4.05 Å and 3.75 Å, respectively. The ratio of the anion-anion pair distance to the cation-anion pair distance (r--/r+-) was, therefore, 1.43, being close to 1.41, characteristic of octahedral geometry. These results indicate that ErCl63--octahedra exist in molten ErCl3. Probably Er2Clio and a small amount of Er2Cl115- ions are formed according to the geometrical calculations of bond lengths and bond angles.

Abstract The structure of molten NdClj at 800 CC has been investigated by X-ray scattering and the correlation method. The nearest neighbor distance and coordination number of Nd-Cl are 2.77 Ä and 5.5 A, respectively. The Nd-Nd and CI-CI distances are 5.08 and 4.04 Ä, respectively. The average nearest neighbor distance and coordination number decrease markedly on melting, and the resulting short range structure of the melt is approximately octahedral
