A new intercalation compound, Mn0.91PS3(pararosaniline)(0.18), is synthesized through the exchange of Mn1-xPS3.K-2x with pararosaniline (HOC(C6H4NH2)(3)) in the presence of chloride acid in methanol. Its structure is characterized by elemental analysis, X-ray diffraction (XRD), infrared spectroscopy. XRD results show that the lattice spacing is expanded by 10.5 Angstrom compared with pure MnPS3, which indicates that the molecular ring plane of the guest is perpendicular to the layer of the host. The infrared absorption spectrum infers that the inserted guest of pararosaniline exists in the cation form to maintain the charge balance of the intercalation compound. The Studies of magnetic properties with SQUID indicate that the intercalation compound exhibited bulk spontaneous magnetization below 40 K.
