MgV4P2O13
MgV4P2O13 is a semiconducting transition-metal phosphate compound that exists as a metastable phase within a complex structural family.
About MgV4P2O13
MgV4P2O13 is a complex transition-metal phosphate characterized by its semiconducting electronic nature. As a member of the phosphate family, it features a structural framework that integrates magnesium and vanadium within an oxygen-phosphorus network, reflecting the structural diversity common to this chemical class. Despite its structural complexity, the compound is identified as being above the thermodynamic hull, suggesting it is a metastable phase. Its existence across multiple reported structures highlights the ongoing interest in exploring the phase space of vanadium-based phosphates for potential functional applications.
Key Properties

How It Compares
Within the transition-metal phosphates class.
Unlike the highly stable and widely utilized olivine-structured materials such as LiFePO4 or LiMnPO4, which are cornerstones of battery technology, MgV4P2O13 represents a more exotic and less thermodynamically favored member of the transition-metal phosphate group. While siblings like LiFeP2O7 are frequently studied for their electrochemical properties, this magnesium-vanadium variant occupies a more niche position due to its metastability.
