Abstract
- The heat capacities of CsPbI <subscript>3</subscript> , Cs <subscript>4</subscript> PbI <subscript>6</subscript> , and Cs <subscript>3</subscript> Bi <subscript>2</subscript> I <subscript>9</subscript> were studied using low-temperature thermal relaxation calorimetry in the temperature range of 1.9-300 K. The three compounds are insulators, with no electronic contribution to the heat capacity. None of them show detectable anomalies in the studied temperature window. Thermodynamic properties at standard conditions are derived. Previously reported results on Cs <subscript>3</subscript> Bi <subscript>2</subscript> I <subscript>9</subscript> are not fully consistent with the present findings. Moreover, the magnetic susceptibilities of the three title compounds were measured.<br />Competing Interests: The authors declare no competing financial interest.<br /> (© 2023 The Authors.
