The Structure of α-Zn4Sb3: Ordering of the Phonon-Glass Thermoelectric Material β-Zn4Sb3. — β-Zn4Sb3 is prepared by heating a pressed pellet of Zn4Sb3 at 923 K
in an evacuated quartz tube. β-Zn4Sb3 transforms around 260 K to a low-temperature
α-form which crystallizes in the triclinic space group C1 with Z = 8 at 150 K as
revealed by single crystal XRD. During the reversible phase transition the intricate disorder in β-Zn4Sb3 disappears and all Zn atoms localize completely. The electronic structure of β-Zn4Sb3 corresponds to that of a narrow-gap semiconductor. An explanation of
the peculiar phonon glass—electron crystal behavior of β-Zn4Sb3 is suggested. —
