Large tunnels in the hydrothermally synthesized open-framework iron phosphate [H3N(CH2)3NH3]2[Fe 4(OH)3(HPO4)2(PO4) 3]·xH2O

Abstract

The synthesis and characterization of a microporous iron phosphate is described; the structure consists of infinite chains of iron–oxygen octahedra linked by phosphate groups to generate large tunnels containing 20-ring windows in which water molecules and the charge-compensating organic cations reside.
