CaSi_2O_2N_2-A Novel Layer Silicate

摘要

Silicates are one of the largest classes of compounds in inorganic chemistry.Most of them are pure oxidic compounds (oxosilicates).SiX_4 tetrahedrons (X = O,N) are a typical feature of almost all previously described oxo- and nitridosilicates.They are connected through common corners (X = O,N) or edges (X = N) and form condensed anionic structures with a wide range of degree of condensation.
