Abstract

The hydrothermal reaction of FeCl2·4H2O, 1,2-[phenelyenebis(methylene)]bis-phosphonic acid (o-C8H8P2O6H4), and triethylamine produced [Fe(o-C8H8P2O6H)(H2O)] as a yellow crystalline solid. The structure consists of two-dimensional networks of Fe(III)O6 octahedra linked through RPO3 tetrahedra. The xylyl groups project above and below these layers into the interlamellar domain. The iron coordination consists of five oxygen donors from five different phosphonate tetrahedra and an aqua ligand. The diphosphonate ligand adopts the [3.111213/2.11140] bonding mode, according to a modified Harris notation.
