Fm 3 m; NaTl type, sp. Fd 3 m ) system. The last structure type includes only theCs compounds Cs 3 Sb and Cs 3 Bi 1.Whereas Na 3 Sb and Cs 3 Sb each exist, at atmo-spheric pressure, in only one polymorph (hexagonalNa 3 Sb and cubic Cs 3 Sb), Li 3 Sb, K 3 Sb, and Rb 3 Sb eachexist in two crystalline forms, a phase (hexagonal) and b phase (cubic), depending on the preparation condi-tions. Cubic K 3 Sb was only obtained in thin-film form2; bulk samples have the hexagonal structure.The phase diagram of Li 3 Sb has not yet beenmapped out; the available data are contradictory.
CubicLi 3 Sb ( b phase) was variously reported to be stablebelow 650 C 3, 4 or above 650 C 5.Na 3 Sb and Na 3 Bi were reported to undergo the hex-agonal-to-cubic phase transition at 1.8 and 1.0 GPa,respectively 6, 7.One way of stabilizing the cubic phase is by prepar-ing ternary compounds via substitutions, e.g., Li 2 NaBi 7, 8, Li 2 NaSb 9, and Na 2 KSb 10. All these com-pounds have the general formula A 2 A'B (A, A' = alkalimetal; B = Sb, Bi) and a cubic structure of the BiF 3 type.
