Abstract
The crystalline stoichiometric phase LiSrN is an isotype of the YCoC structural type, which was first determined in 1986 by X-ray powder methods. Thus, this very simple structural type is not limited to transition-metal carbides. The metal cations Li and Sr form an arrangement previously observed in the CsCl structure. The anions (inside the polyhedron) occupy the centers of opposite faces of the (compressed) cube. LiSrN contains extended chains of [LiN]2⊖, the N atoms of which achieve rhombic-pyramidal coordination by additional contacts to four Sr atoms.
