The cover picture shows a section of the crystal structure of the first nitridoscandate Li 3 [ScN 2 ], in which for the first time Sc is observed in tetrahedral coordination. A the periodic nodal surface (PNS: grey mesh) separates Li + atoms from the ${^{3}_{\infty }}$ [ScN ${_{4/2}^{3-}}$ ] network. Two isosurfaces of the electron localization function (ELF) at η =0.85 (light yellow) and η =0.74 (transparent orange) show the structuring of the outer‐core localization domain of Sc and the valence localization domain of N, respectively.
