Synthesis, Characterization, and Magnetic Properties of Intercalation Compound of 1,10-Phenanthroline with Layered MnPS3

A new intercalation compound Mn0.84PS3(phen)0.64 (phen=1,10-phenanthroline) was synthesized in one step by direct reaction of host MnPS3 with 1,10-phenanthroline, which was characterized by elemental analysis, X-ray powder diffraction, and infrared spectroscopy. As a result of intercalation, the lattice spacing of the intercalate expanded by 8.63 ? with respect to the pristine MnPS3. For comparison, another new intercalation compound Mn0.88PS3[Mn(phen)4]0.12(H2O) was also prepared in two steps by means of ion exchange. The studies of magnetic properties with SQUID-magnetometer indicated that the two intercalates, Mn0.84PS3(phen)0.64 and Mn0.88PS3[Mn(phen)4]0.12 (H2O), exhibit bulk spontaneous magnetization below 36 and 33 K, respectively
