Abstract
[Abstract] We report that the hybrid organic–inorganic compound [(CH₃)₂NH₂][Mg(HCOO)₃] shows a marked dielectric transition around Tₜ ∼ 270 K, associated to a structural phase transition from SG R[3 with combining macron]c (centrosymmetric) to Cc (non-centrosymmetric). This is the highest Tₜ reported so far for a perovskite-like formate that is thus a promising candidate to display electric order very close to room temperature.
