Abstract
A new series of inorganic-organic hybrid materials, 2 ' -R-1-4 ' -R-2-N-met hylstilbazoliums (a, R-1 = R-2 = MeO; b, R-1 = R-2 = Cl; c, R-1 = R-2 = H: d, R-1 = H, R-2 = MeO; e, R-1 = H, R-2 = Cl) intercalated into lamellar FeP S3, were synthesized through ion-exchange process. Compared with FePS3(d = 6.42 Angstrom), the lattice spacing expansion (Deltad) of 14.6 Angstrom for Intercalate a, 13.2 Angstrom for Intercalate b and 5.7 similar to 6.0 Angs trom for Intercalate c, d and e indicated that the molecular ring planes of the guests are perpendicular to the layers of the host. Among them the lat tice spacing of 21.02 Angstrom for Intercalate a is the largest for all FeP S3 intercalates reported. Their magnetic properties were studied, all of wh ich exhibited the similar antiferromagnetic properties with Neel temperatur e at around 80 K. It seems that the lattice spacing expansion and the elect ron-effect of substitution group of the guest have little influence on the magnetic properties for these intercalates.
