Synthesis and structure of an open-framework chlorophosphate,[C₆NH₁₄][ZnCl(HPO₄)]

Abstract

A zinc chlorophosphate, of the composition [C₆NH₁₄][ZnCl(HPO₄)], with a layered architecture has been synthesized, for the first time, in the presence of cyclohexylamine as the structure-directing agent. The structure comprises a network of ZnO₃Cl and PO₄ tetrahedra forming macroanionic layers with four- and eightmembered apertures. Charge compensation is achieved by the protonated amine occupying inter-lamellar space and interacts with the framework via hydrogen bonding. The crystal structure of the new compound was determined.
