A corrugated [Si 2 O 2 N 2 ] 2− layer anion , which is constructed of dreier rings, forms the basis of the silicate Ca[Si 2 O 2 N 2 ] (see picture). The unusual structure results from the fact that every N atom—unlike the O atoms in oxosilicates—links three neighboring Si tetrahedron centers within the layers, whereas all the O atoms are exclusively bonded terminally to the Si atoms.
