Abstract

Cd13-x;In7Sb10 (x≈2.7, Y≈ 1.5) was synthesized in the form of millsized crystals from reaction mixtures containing excess cadmium. The intermetallic compound crystallizes in the rhombohedral space group R3m with α = 12.9704(4), c= 12.9443(5) Å, V= 1886.0(1) Å3, Z=3 and is isostructural to thermoelectric ß-Zn 4Sb3 and ßCd4Sb3. However, in contrast to these last two compounds Cd13-xInySb 10 is free from interstitial atoms and does not display any temperature polymorphism. The electrical resistivity of Cd13-xIn ySb10 is considerably higher than that of Zn 4Sb3 and... (More)

Cd13-x;In7Sb10 (x≈2.7, Y≈ 1.5) was synthesized in the form of millsized crystals from reaction mixtures containing excess cadmium. The intermetallic compound crystallizes in the rhombohedral space group R3m with α = 12.9704(4), c= 12.9443(5) Å, V= 1886.0(1) Å3, Z=3 and is isostructural to thermoelectric ß-Zn 4Sb3 and ßCd4Sb3. However, in contrast to these last two compounds Cd13-xInySb 10 is free from interstitial atoms and does not display any temperature polymorphism. The electrical resistivity of Cd13-xIn ySb10 is considerably higher than that of Zn 4Sb3 and Cd4Sb3 although the temperature behavior remains that of a metal. The thermal conductivity of Cd13-xInySb10 is low, with room-temperature magnitudes around 0.8Wm-1K-1, which is comparable to disordered or complex structured Cd4Sb3 and Zn 4Sb3.
