Cs2Al2P2O9: an exception to Löwenstein’s rule. Synthesis and characterization of a novel layered aluminophosphate containing linear Al–O–Al linkages

Abstract

A caesium aluminophosphate compound synthesized via high-temperature, solid-state methods reveals a new composition for a layered AlPO structure; it exhibits a non-Löwensteinian framework which contains linear Al–O–Al linkages in six-rings of alternating Al₂O₇ and PO₄ groups.
