Three bioorganic-inorganic hybrid nanocomposites based on amino acids into layered MnPS{sub 3} have been synthesized and characterized with powder X-ray diffraction (XRD), infrared spectroscopy (IR) and elemental analysis. The expanded MnPS{sub 3} structure as well as the characteristic IR absorption supports the successful and full intercalation of amino acids as the guests into interlayered space of MnPS{sub 3} host. The lattice spacing expansion from XRD patterns indicates that the inserted guest is arranged in the monolayer with carbon chain parallel to the layer of MnPS{sub 3}. The magnetic measurements indicate that all three nanocomposites show paramagnetism above 50 K and obey Curie-Weiss law; however, at T {sub c} of 40 K a ferrimagnetic transition is observed. The hysteresis of magnetization (M) versus magnetic field (H) at 1.85 K further confirms that these intercalation compounds are low-temperature ferrimagnets.
