Heat capacity of single-crystal samples of five chalcogenides (LiInS2, LiInSe2, LiGaS2, LiGaSe2, and LiGaTe2) was measured with DSC in a temperature range from 180 to 460 K. The data for LiInS2 and LiInSe2 were compared with the literature data and shown to agree with the results of adiabatic calorimetry (Gmelin and Hönle in Thermochimica Acta 269: 575–590, 1995) better than with other DSC data (Kühn et al. in Cryst Res Technol 22: 265–269, 1987). Besides, the high-temperature fitting polynomial for CP(T) published about 30 years ago for LiInS2 is wrong. LiGaS2, LiGaSe2, and LiGaTe2 were measured for the first time.
