Abstract

The coefficients of thermal expansion of three ternary chalcogenides of molybdenum Tl2Mo6Se6, Cs2Mo6Se6, and Na2Mo6Se6 have been determined in the temperature range 16 to 400° C using a Guinier-Lenne camera and a powder diffractometer. In all the three compounds, the coefficient of expansion along thec-axis (α∥) is found to be much smaller than that in the perpendicular direction (α⊥). This behaviour has been explained in terms of the strength of the interatomic bonds in the two directions.
