Novel inorganic-organic hybrid nanosheet was found in the precursor for synthesizing Fe₃O₄ nanocrystal. This nanosheet was prepared by solvothermal technique. The chemical composition is determined as [Fe₇(C₂H₄O₂)₉]_nO_y. Although its crystal structure has not been clarified, yet, some experimental data implies the hybridization state of inorganic oxide matrix in the framework of organic molecules. The magnetism shows antiferromagnetic behaviour with low dimensional character. These characteristics are quite interesting, since it is not common for generally known iron oxides.
