Abstract Intercalation compound FePS3(CoCp2)0.40 (CoCp2 = cobaltocene) was synthesized, and the crystal structure and magnetic properties were studied by x-ray diffraction, magnetic susceptibility measurement, and Mössbauer spectroscopy. The crystal structure was indexed to monoclinic unit cell with a = 5.996Å, b = 10.106Å c = 12.511Å, β = 105.916°, and about 5.6Å expansion at the c direction compared to pure FePS3. The Mössbauer spectra indicate that there are three kinds of divalent irons with high spin state in the intercalation compound, which implies that charge transfer from guest to the Fe-S e*g anti-bonding orbits of host lattice. No cationic vacancies are formed in the intercalation compound. The ferromagnetism at low temperature originates from the spin canting of divalent irons.
