The standard molar enthalpy of formation of indium monotelluride InTe(cr) was refined and found to be -(71.2 + 0.3) kJ . mol(-1). The standard molar change of energy at the temperature 298.15 K for the reaction : In4T3(cr) + Te(cr) = 4InTe(cr) was determined; the standard molar enthalpy of formation of In4TeJ(cr) was calculated to be -(235.5 +/- 1.8) kJ . mol(-1) (here and elsewhere in the paper the uncertainties are given for a 95 per cent confidence interval).
