| Abstract: A 3-D open framework iron phosphate [NH3CH2CH2NH3]0.5[FePO4], which contains organic ethylenediammonium dication in the framework voids, has been synthesized under solvothermal conditions and has been characterized by single crystal diffraction, IRspectrum, Mssbauer spectroscopy and thermogravimetric analysis. The compound crystallizes in the orthorhombic space group with a =10.361(6)Å, b =10.390(5)Å, c =9.135(7)Å, V =983.3(11)Å3,Z=8.The structure consists of corner sharing FeO4 and PO4 tetrahedra to form an open framework structure with eight membered ring channels along [001] direction. This new material was obtained by use of iron power as iron source in ethylene glycol solvent. The most important feather of the compound is that it contains four coordinated iron atoms which is very rare in iron phosphates. |
