Abstract
Neutron diffraction studies of the superionic conductor Li0.25Cu1.75Se are reported. It is shown that gradual disordering in the cation sublattice with an increase in temperature leads to changes in the symmetry of the crystal lattice at 400 and 500 K. At temperatures close to these values, anomalies in the temperature dependence of both ionic and electron conductivity are observed.
