Four silicon atoms have been connected to one central nitrogen atom for the first time in BaYbSi 4 N 7 . These N [4] bridges significantly extend the spectrum of possible linkages in Si ‐ N network structures of nitridosilicates. While oxosilicates are built up by SiO 4 tetrahedra with either terminal oxygen atoms or simply bridging O [2] atoms, the N [2] , N [3] , and N [4] linkages in nitridosilicates enable novel highly cross‐linked SiN network structures.
