The heat capacities of CsPbI3, Cs4PbI6, and Cs3Bi2I9 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 Cs3Bi2I9 are not fully consistent with the present findings. Moreover, the magnetic susceptibilities of the three title compounds were measured.

CsPbI3、Cs4PbI6 和 Cs3Bi2I9 的低温热容
使用低温热弛豫量热法研究了 CsPbI 3 、Cs 4 PbI 6和 Cs 3 Bi 2 I 9的热容，温度范围为 1.9–300 K。这三种化合物是绝缘体，对电子没有贡献。热容量。它们都没有在研究的温度窗口中显示出可检测到的异常。推导出标准条件下的热力学性质。先前报道的 Cs 3 Bi 2 I 9结果与目前的发现并不完全一致。此外，测量了三种标题化合物的磁化率。
