Non-collinear magnetism in the post-perovskite thiocyanate frameworks CsM(NCS)₃.

ABSTRACT: AMX₃ compounds are structurally diverse, a notable example being the post-perovskite structure which adopts a two-dimensional framework with corner- and edge-sharing octahedra. Few molecular post-perovskites are known and of these, none have reported magnetic structures. Here we report the synthesis, structure and magnetic properties of molecular post-perovskites: CsNi(NCS)₃, a thiocyanate framework, and two new isostructural analogues CsCo(NCS)₃ and CsMn(NCS)₃. Magnetisation measurements show that all three compounds undergo magnetic order. CsNi(NCS)₃ (Curie temperature, T _C = 8.5(1) K) and CsCo(NCS)₃ (T _C = 6.7(1) K) order as weak ferromagnets. On the other hand, CsMn(NCS)₃ or
