Abstract

The structure of the ionic glasses (KCl)x(BiCl3)1-x where x = 0.35, 0.40, 0.45, has been measured at 20 K by using neutron diffraction. The results show that BiCl3 units exist as the predominant structural motifs at all compositions, give a Bi-Cl nearest-neighbour distance of 2.53(2) Å, and an angle Cl-Bi-Cl of 89(2)°. The nearest-neighbour K-Cl correlations occur at about 3.1 Å. The first sharp diffraction peak observed in the total structure factors is attributed to Bi-Bi correlations and the shift in its position to smaller scattering vector values with increased x is attributed to an enlarged separation of the BiCl3 units with enhanced KCl content.
