Non-oxide microporous solids

The preceding discussion of inorganic microporous structures illustrates the great variety of metal eations that may be accommodated in porous frameworks. By contrast, relatively little progress has been made in the preparation of porous frameworks with anions other than oxide ions. The obvious candidates are nitrides and sulfides and there have been some reeent advances in these directions. 

Schnick and co-workers, for example, have prepared nitridophosphates with zeolite-like frameworks by high-temperature routes, including analogues of
