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-phenanthrol ine) was synthesized in one step by direct reaction of host MnPS3 with 1,10 -phenanthroline, which was characterized by elemental analysis, X-ray powde r diffraction, and infrared spectroscopy. As a result of intercalation, the lattice spacing of the intercalate expanded by 8.63 Angstrom with respect to the pristine MnPS3. For comparison, another new intercalation compound M n0.88PS3[Mn (phen)(4)](0.12)(H2O) was also prepared in two steps by means o f 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 an d 33 K, respectively.
