Noncentrosymmetric (NCS) materials are of great significance for electronics and photonics as the lack of an inversion center enables the occurrence of ferroelectricity and second-harmonic generation. Recently NCS magnetic compounds enjoy a renewed research interest due to the possibility of hosting non-trivial spin textures, including magnetic skyrmions. However, NCS materials are in general uncommon: only about one in six compounds reported in the Inorganic Crystal Structures Database (ICSD) is acentric. In our recent reports, we describe how anionic building blocks featuring stereoactive lone pairs can be employed to explore new noncentrosymmetric magnetic materials featuring interesting magnetic structures and optical properties.
