The temperature dependences of the total vapour pressure for solid and liquid InI 2 and liquid InI 3 were measured by the static method with a membran‐gauge manometer. The heat capacities above phases and solid InI 3 were also obtained. The partial pressures In 2 I 6 , InI 3 , InI, In 2 I 4 , I 2 , I were calculated. Absolute entropies and enthalpies of formation InI 2 (crII), InI 2 (l), In 2 I 4 (g), InI 3 (l), InI 3 (g), In 2 I 6 (g) were obtained. We used the least square method to obtain the mutual consistent sets of data on thermodynamic characteristics of indium iodides in condensed and gaseous phases. The result of this work is the set of standard formation enthalpies and absolute entropies of the In–I system compounds.
