Syntheses and structures of the openframework phases (CH3NH3)3·Zn4O(AsO4)3 and (CH3NH3)3·Zn4O(PO4)3 related to the M3Zn4O(XO4)3·nH2O family

Abstract

The solution-mediated syntheses and single crystal structures of the new open-framework phases (CH3NH3)3·Zn4O(AsO4)3 and (CH3NH3)3·Zn4O(PO4)3 are reported. These compounds are built up from vertex-sharing three-dimensional “OZn4” + ZnO4 + AsO4/PO4 tetrahedral frameworks encapsulating methylammonium cations in three-dimensional channel systems. These phases are closely related to the zeolite-like M3Zn4O(XO4)3·nH2O family of phases.
