Thermal expansion of ternary chalcogenides of molybdenum containing infinite chains of (Mo6/2Se6/2)

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.
