Low-temperature synthesis of hydrated zinco(beryllo)-phosphate and arsenate molecular sieves

Kristallstruktur und hydrothermale Darstellung der Schichtverbindung Be2(PO4)(OH)·2H2O / Crystal Structure and Hydrotherm al Synthesis of the Layered Compound Be2(PO4)(OH)·2H2O

“…Weitere Paralle len zu bekannten Alumosilicaten wie z. B. Zeoli then der Typen L i-A (B W ), Edingtonit und Gis mondin wurden bestätigt [2][3][4]. D aneben treten auch Beryllophosphate auf, für die im Bereich der Alumosilicate keine Strukturäquivalente bekannt sind.…”

The Interface of Nanoscale Inclusion Chemistry

“…A consideration of tetrahedral radii does suggest that other elements might be used ( Table H]). Recently, the syntheses of zeolite structural analogues containing elements from Groups 2 (IIA) and 12 (JIB) at temperatures as low as -20"C have been reported (57,(62)(63)(64)(65). The molecular sieve chemistry of these new framework compositions is extensive.…”

3-D Periodic Packaging: Sodalite, a Model System

“…Using beryllium or zinc as framework metal atoms, we have isolated a number of open framework structures at room temperature or lower (27), (30), (48), (49) well within the regime of solvent clathrate templating. The molecular sieve chemistry of these new framework compositions is extensive.…”
