CoIn2
CoIn2 is a metallic, metastable intermetallic compound formed from cobalt and indium that is characterized by a high degree of structural diversity.
About CoIn2
CoIn2 is a metallic intermetallic compound composed of cobalt and indium. As a metastable phase, it represents a specific configuration of these transition metal and post-transition metal elements that exists outside of the primary equilibrium state.
Its significance lies in its structural complexity, evidenced by multiple reported crystalline arrangements across various databases. This diversity makes it a subject of interest for researchers studying phase stability and the formation of intermetallic systems.
Key Properties
Cross-validated computational properties for CoIn2, 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.
StructuresCount of reported calculated crystal structures for this formula, including alternate polymorphs, source databases, and observed space groups.
Cross-Source DFT Agreement
How well independent DFT databases agree on the thermodynamics of CoIn2. Tight agreement means computed properties can be trusted without re-running calculations.
Agreement ScoreA normalized confidence score summarizing how closely independent DFT databases agree. Higher scores mean tighter cross-source agreement.
Hull SpreadDifference between the highest and lowest energy-above-hull values reported by comparable sources. Smaller spread means less thermodynamic disagreement.

How It Compares
As a distinct intermetallic phase, CoIn2 serves as a case study for the complex interplay between cobalt and indium bonding. Without a broader family of closely related compounds to compare against, its behavior is primarily defined by its unique metastable nature and the varied structural pathways it exhibits in solid-state synthesis.
