Mn2P
Mn2P is a thermodynamically stable, metallic manganese phosphide characterized by a high degree of structural documentation.
About Mn2P
Mn2P is a metallic manganese phosphide that occupies a stable position on the thermodynamic convex hull. Its robust structural identity is evidenced by its extensive representation across multiple materials databases, highlighting its significance in solid-state chemistry.
As a metallic compound, it serves as a foundational material for studying transition metal-phosphorus interactions. Its stability and well-documented structural diversity make it a key subject for researchers investigating the fundamental properties of binary phosphides.
Key Properties
Cross-validated computational properties for Mn2P, aggregated across 5 databases.
Band GapEnergy needed to move an electron from the valence band to the conduction band. Lower or zero values tend to behave more metallic; larger gaps are more insulating or semiconducting.
Energy Above HullThermodynamic distance from the most stable set of competing phases. 0 eV/atom is on the convex hull; small positive values may still be experimentally accessible.
StabilityA plain-language summary of the best reported energy-above-hull result. It reflects whether the lowest-energy structure is on, near, or far from the stability hull.

Reported Structures
Lowest-energy structures reported for Mn2P, ranked by energy above hull.
| Space GroupSymmetry classification of the crystal arrangement. The number is the international space-group index. | Crystal SystemBroad lattice family, such as cubic, tetragonal, monoclinic, or triclinic, derived from unit-cell symmetry. | Band Gap (eV)Electronic gap calculated for this specific reported structure, measured in electronvolts. | E above hull (eV/atom)Thermodynamic distance from the convex hull for this structure, normalized per atom. Lower is generally more stable. | E/atom (eV)Computed total energy normalized per atom. Use energy above hull, not this value alone, when comparing stability. | Density (g/cm³)Mass per relaxed crystal volume, reported in grams per cubic centimeter. |
