About MnCN
MnCN is an intriguing inorganic compound composed of manganese, carbon, and nitrogen. As a semiconducting material, it represents a unique intersection of transition metal chemistry and cyanide-based coordination, offering potential for specialized electronic applications.
While the compound is currently categorized as thermodynamically unstable relative to its decomposition products, it remains a subject of interest for researchers investigating metastable phases. Its existence across multiple reported structures highlights the complexity of its bonding environment and the challenges in synthesizing stable configurations.
Key Properties
Cross-validated computational properties for MnCN, aggregated across 3 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.
