Abstract

Exfoliation-restack method has been employed to synthesize the intercalation compounds based on the cationic complexes [M(Salen)]+ (M = Mn3+, Fe3+, Co3+; Salen = N, N′-ethylene-bis(salicylaldimine)) into the layered MoS2. Their conductivity is in the range of 0.04–0.1 S/cm, which is much higher than the pristine MoS2. Magnetic measurement indicated that the intercalation compounds [Mn(Salen)]0.18MoS2 · 0.25H2O and [Fe(Salen)]0.12MoS2 · 0.3H2O exhibit the temperature-dependent paramagnetism, which obviates from the Curie–Weiss law due to the temperature-independent paramagnetism of the exfoliated MoS2 slabs, while [Co(Salen)]0.14MoS2 · 0.5H2O exhibits the almost temperature-independent paramagnetism. All three intercalation compounds do not show magnetic spin crossover behavior.
