“…For instance, it was reported that there is a strong tendency in MnPS 3 and FePS 3 for cation exchange, along with the creation of M 2+ vacancies during intercalation. 15,16,19–21 In contrast, no direct intercalation of pyridine was observed for NiPS 3 , although metal-to-ligand interaction would be of a similar bond strength. 22 Pattayil et al suggested that a possible reason for this is the difference in the crystal field energy, which stabilizes Ni in the crystal structure, 22 thereby impeding the pyridine intercalation.…”
