FeI3K
FeI3K is a metastable, semiconducting ternary compound consisting of iron, iodine, and potassium.
About FeI3K
FeI3K is a ternary compound composed of iron, iodine, and potassium. As a semiconducting material, it represents a complex arrangement of transition metal halides that bridges the gap between simple binary salts and more intricate coordination frameworks. Its electronic properties suggest potential for specialized optoelectronic research despite its complex structural nature.
This compound is characterized by its position above the thermodynamic hull, indicating that it is likely unstable under standard conditions. While multiple structural configurations have been identified across various databases, its synthesis remains a challenge due to its inherent metastability, making it a subject of interest for computational materials science and high-pressure experimental studies.
Key Properties
