Correlations between the cohesive energy per mole and a crystallographic ratio in alkali chalcogenides are presented. The linear relationship is found to be valid so far for crystals with NaCl and antifluorite structure. This work highlights the significance of the anion radius in determining the cohesive energy in alkali chalcogenides.
