Na_2Zn_3(CO_3)_4 centre to 3H_2O, a Mieroporoas Sodium Zineoearbonate with a Diamond-Type Tetrafaedral-Triangular Topology

摘要

Microporous open frameworks, built from comer sharing of tetrahedra of suitable metal(oid) atoms and oxygen atoms, are well-known. Zeolites (aluminosilicates) are produced synthetically in ton quantities annually for a variety of commercially important uses. In the 1980's, open frameworks based on aluminum and phosphorus tetrahedra (AIPO's) were discovered, many with structures analogous to some of the zeolites despite the fact that the frameworks were neutral instead of negatively charged. More recently, a wide variety of microporous structures based on zinc, beryllium, phosphorus, and arsenic tetrahedra have been demonstrated.
