An inorganic–organic intercalated nanocomposite, BEDT-TTF into layered MnPS3

In this paper we report the synthesis and magnetic properties of an inorganic–organic hybrid, Mn0.84PS3(BEDT-TTF)0.35 (BEDT-TTF = bis(ethylenedithio) tetrathiafulvalene), which is obtained by the intercalation of pre-intercalation compound Mn0.90PS3(Phen)0.32 (Phen = 1,10-phenanthroline) with (BEDT-TTF)2Ix. The lattice spacing expansion (Δd) of 4.0 Å compared with the pristine MnPS3 indicates that the molecular plane of BEDT-TTF is arranged parallel to the host layer. From the magnetic measurements it was found that two magnetic phase transitions occur. Above 50 K it shows paramagnetism in well agreement with Curie–Weiss law. Around 40 K it exhibits spin-glass transition and at 5 K a ferrimagnetic phase transition occurs, which is confirmed by M–H at different temperatures.
