Abstract

We report the synthesis, crystal structure, thermal, dielectric, phonon and magnetic properties of the [CH₃C(NH₂)₂][Mn(HCOO)₃] (AceMn) compound. Our results show that this compound crystallizes in the perovskite-like orthorhombic structure, space group Imma. It undergoes a structural phase transition at 304 K into a monoclinic structure, space group P2₁/n. X-ray diffraction, dielectric, IR and Raman studies show that the ordering of the acetamidinium cations triggers the phase transition. Low-temperature magnetic studies show that this compound exhibits weak ferromagnetic properties below 9.0 K.
