Low‐symmetric quasi‐spherical cations have been widely used in halogenometallate hybrids to increase the incidence of stimulus‐responsive crystal structures. In this paper, we successfully used triethylmethylammonium bromide and cadmium bromide for self‐assembly to obtain a A₂BX₄‐type hybrid compound [TEAMA]₂[CdBr₄] (TEAMA=(CH₃CH₂)₃NCH₃, 1) showing phase transition temperature (T_c) of 333 K above room temperature. Various‐temperature structures of 1 have been measured by X‐ray diffraction. We conclude, the phase transition property of 1 induced by thermal stimulation stems from the thermal ellipsoids of the [TEAMA]⁺ become strikingly larger with the increase of the temperature. The dynamics of the dipoles is the key to construct hybrid molecule‐based switchable dielectrics by motional changes of polar components at different phases. Furthermore, the dielectric properties have also been mentioned and discussed in great detail.

A2BX4型混合化合物中具有温度诱导的可逆介电转换和可切换介电响应：[TEAMA] 2 [CdBr4]（TEAMA =（CH3CH2）3NCH3）

低对称的准球形阳离子已广泛用于卤代金属盐杂化物中，以增加刺激响应晶体结构的发生率。在本文中，我们成功地使用三乙基溴化铵和溴化镉为自组装以获得阿₂ BX ₄型混合化合物[TEAMA] ₂ [CDBR ₄ ]（TEAMA =（CH ₃ CH ₂）₃ NCH ₃，1）显示出高于室温333 K的相变温度（T _c）。通过X射线衍射测量了1的各种温度结构。我们得出结论，由热刺激引起的图1中，[TEAMA] ⁺的热椭球体随温度升高而显着变大。偶极子的动力学是通过不同阶段极性成分的运动变化来构建基于混合分子的可切换电介质的关键。此外，介电特性也已被提及和详细讨论。
