Introduction

The ternary compound Li₂AgBi has been reported by [68Pau1, 68Pau2]. It was prepared by melting the elements in a sealed Fe crucible under dry Ar, shaking to homogenise and air cooling to room temperature. No annealing treatment was given to the solidified compound. [68Pau1] determined the crystal structure to be TiCuHg₂ structure type (cF16, F43m) with a lattice parameter a of 673.6 pm and an X-ray density of 7.19 g•cm^-3. The sample contained a small amount of another, unidentified, phase. [68Pau2] examined four compositions on the section LiAg-LiBi. Homogeneous Li₂AgBi has a lattice parameter a = 673.7 pm. An alloy on the Bi-rich side, Li₂Ag_0.8Bi_1.2, was heterogeneous but the Li₂AgBi phase it conta...
