FePSe3 is a layered metal chalcogenogenide compound combining iron with phosphorus and selenium in a structured lattice. This material is primarily of research interest rather than established industrial production, belonging to the family of transition metal phosphorus chalcogenides that are being explored for next-generation electronic and energy storage applications. The weak interlayer bonding characteristic of this compound makes it a candidate for exfoliation into 2D nanosheets, positioning it within the broader context of van der Waals materials for flexible electronics, catalysis, and quantum device research.
