The Characterization and Magnetic Properties of Inorganic-Organic Hybrid Nanocomposites, Stilbazoliums Inserted into Layered FePS3

Five inorganic-organic intercalation compounds (I–V) with N-methylstilbazoliumderivatives (i–v) inserted into the interlayer space of FePS3, were synthesized,and characterized with X-ray diffraction (XRD), elemental analysis and infraredspectroscopy. The XRD results indicate that in all these intercalation compounds themolecular ring planes of the guests are almost perpendicular to the layers of thehost FePS3. From the lattice expansion of intercalates IV and V itcan be inferred that a dipolar interaction may exist between the guests in theinterlayer space of the host FePS3. Their magnetic properties were measuredwith the SQUID technique. All these intercalation compounds show similar magneticproperties. At the Neel temperature of about 80 K they exhibit the antiferromagnetictransition, although the lattice spacing and the electron-accepting ability of theguest are different. It may imply that the lattice spacing expansion and an electron-effectof the guests have not altered their antiferromagnetic property of these FePS3intercalation compounds.
