  • Abstract
    The crystal structures of the α- and β-Zn4Sb3 have been investigated by the synchrotron-radiation X-ray powder diffraction at temperatures of 180 to 295 K. The Rietveld analysis indicates that the α-Zn4Sb3 possesses a rhombohedral structure with R-3c as the β-Zn4Sb3 does. The β- to α-phase structural transition is of 2nd order and accompanies the reduction in the c/a and increase in volume (Δa/a>0 and Δc/c<0). The atomic displacement parameters and bond distance are calculated.
