Abstract: The synthesis and magnetism of an intercalation compound were studied based on 2-(4′-N-methylpyridini-um)-4,4,5,5-tetramethyl-imidazolinyl-1-oxyl-3-oxide (Methylpyridinium nitronyl nitroxide, MPYNN) radical into lay-ered MnPS3. The lattice expansion of 0.56 nm suggests that the guest molecule plane of pyridine in MPYNN is arranged almost perpendicular to the host layer. Magnetic measurements by SQUID indicates that the intercalation compound of (MPYNN)0.14Mn0.93PS3 exhibits paramagnetism above 10 K, and then spontaneous magnetization occurs at 7 K.
