β¦ Synopsis
A new iron phosphate, [C 2 N 2 H 10 ] 2 [Fe 5 F 4 (PO 4 )(HPO 4 ) 6 ], containing F Ψ ions as part of the framework, has been synthesized hydrothermally using iron acetylacetonate as the source for iron and ethylenediamine (en) as the amine. A network of [Fe(O/F) 6 ] octahedra and PO 4 tetrahedra, linked through their vertices, forms the three-dimensional architecture with one-dimensional channels bound by 8-T atom (T β«Ψβ¬ Fe, P), wherein the disordered en molecules are located. The connectivity between the Fe centers via Fe+O/F+Fe linkage giving rise to a pentamer unit is worthy of note.
