Unlike previously studied members, Cs$_2$CoI$_4$ undergoes a structural phase transition, for which we determine the low-temperature crystallographic structure. The resulting symmetry reduction strongly affects both the magnetic exchange interactions and single-ion anisotropy. Despite the large parameter space, we propose a minimal magnetic Hamiltonian that rea","authors_text":"A. Zheludev, D.G. Mazzone, D.R. Allan, D. Sheptyakov, H. Kikuchi, J. Lass, K. Yu. Povarov, L.
