Abstract: | TlFe3Te3 is hexagonal, space groupP63/m–C
2h

,a=9.350(2) Å,c=4.2230 (7) Å,Z=2. Iron and tellurium atoms occupy the positions 6 (h) withx=0.170,y=0.149 andx=0.046,y=0.357 respectively. Thallium atoms are situated in 2 (d). The structure was determined on the basis of single crystal data obtained form a four circle diffractometer. Refinement yielded andR-value of 4.8% for an asymmetric set of 267 reflections. TlFe3Te3 is a new structure type. The structure and its relations to the Mn5Si3–, the Nb3Te4-and the Tl
x
V6S8-type are discussed. |
