NaSb(PS3)2

NaSb(PS3)2 is a layered metal phosphide chalcogenide compound containing sodium, antimony, phosphorus, and sulfur, belonging to the family of van der Waals materials with quasi-2D crystal structure. This is primarily a research material under investigation for its potential in energy storage, thermoelectric, and optoelectronic applications, where the layered architecture and mixed-valence composition offer tunable electronic properties distinct from conventional semiconductors. Interest in this compound stems from its structural similarity to other transition metal phosphide chalcogenides that show promise for battery electrodes, photodetectors, and solid-state device integration where layer-dependent physics can be exploited.
