Complex chalcogenides in the MPS3 family of materials (M = Mn, Fe, Co, and Ni) display remarkably different phase progressions depending upon the metal center orbital filling, character of the P–P linkage, and size of the van der Waals gap. There is also a stacking pattern and spin state difference between the "lighter" and "heavier" transition metal-containing systems that places CoPS3 at the nexus of these activities - even though this compound is under-explored from a properties point of view.
