Synthesis and Magnetic Properties of the Multiferroic [C(NH(2))(3)]Cr(HCOO)(3) Metal–Organic Framework: The Role of Spin–Orbit Coupling and Jahn–Teller Distortions

[Image: see text] We report for the first time the synthesis of [C(NH(2))(3)]Cr(HCOO)(3) stabilizing Cr(2+) in formate perovskite, which adopts a polar structure and orders magnetically below 8 K. We discuss in detail the magnetic properties and their coupling to the crystal structure based on first...

description [Image: see text] We report for the first time the synthesis of [C(NH(2))(3)]Cr(HCOO)(3) stabilizing Cr(2+) in formate perovskite, which adopts a polar structure and orders magnetically below 8 K. We discuss in detail the magnetic properties and their coupling to the crystal structure based on first-principles calculations, symmetry, and model Hamiltonian analysis. We establish a general model for the orbital magnetic moment of [C(NH(2))(3)]M(HCOO)(3) (M = Cr, Cu) based on perturbation theory, revealing the key role of the Jahn–Teller distortions. We also analyze their spin and orbital textures in k-space, which show unique characteristics.
