Synthesis and crystal structure of the first two-dimensional inorganic/organic composite solid of iron(III) molybdate

A novel two-dimensional inorganic-organic composite solid material of iron(III) molybdate [enH2][Fe2(MoO4)4] (1) (en=ethylenediamine) has been hydrothermally synthesized and structurally characterized by elemental analysis, IR spectra, and X-ray diffraction analysis. The sheet structure is constructed by binuclear {FeO6} octahedra and bridging {MoO4} tetrahedra. The two iron octahedra are edge-shared, and all of the oxygen atoms in iron coordination spheres are provided from the {MoO4} tetrahedral units which interconnect the diiron core through the corner sharing, leading to a novel two-dimensional framework.
