Two new intercalation compounds Fe0.90PS3(phen)0.41 (1) (phen stands for 1,10-phenanthroline including a part of 1, 10-phenanthroline H+) and Fe0.83PS3(bipy)0.34 (2) (bipy stands for 2,2’-bipyridine H+ ) were synthesized by the reaction of the layered FePS, with 1,10-phenanthroline or 2,2’-bipyridine in the presence of anilinium chloride. They were characterized by elemental analyses, powder X-ray diffraction (XRD), infrared spectroscopy. The lattice spacing of the intercalate was expanded by 0.90 nm for Fe0.90PS3(phen)0.41 and 0.57 nm for Fe0.83PS3(bipy)0.34 withrespect to the pristine FePS3, indicating that the ring plane of the guests is perpendicular to the layer of the host. The UV-vis absorption spectra of the filtrate in preparation of the intercalates indicate that 1, 10-phenanthroline or 2,2’-bipyridine also acts as a complexing agent to remove intralamellar Fe2+ ions into the solution during intercalation. The magnetic properties of 1 and 2 were studied.
