35_17/1996The cover picture shows a polyhedral representation of the structure of the nitridosilicate BaYbSi4N7. The overall SiN network structure in this compound consists of star-shaped [N(SiN3)4] building blocks (blue). Here for the first time nitrogen atoms (red) that covalently bridge four silicon atoms were discovered. The nitridosilicates thus have significantly more possibilities for forming different structures than the oxosilicates. More about these fascinating results in solid-state chemistry is reported by H. Huppertz and W. Schnick on pages 1983–1984.
