Abstract
The structure of cubic Hg3TeI4 was determined from powder data. The fo
ur positions of the cubic closest-packing of the anions are statistica
lly occupied by 0.8 Te-atoms and 3.2I-atoms. The two types of tetrahed
ral holes are occupied to the extent of 2/4 and 0.4/4, respectively, b
y Hg-atoms. With an ordered model of lower symmetry, the stoichiometri
c composition can be explained and a homogeneous charge distribution c
an be achieved. The ordered model contains regions of the structure of
red HgI2, which are connected by fragments of the SiS2-type.
