Ta2CrNO5
Ta2CrNO5 is a semiconducting tantalum-chromium oxynitride compound that exhibits complex structural diversity and metastable thermodynamic characteristics.
About Ta2CrNO5
Ta2CrNO5 is a complex inorganic compound composed of tantalum, chromium, nitrogen, and oxygen. As a semiconducting material, it occupies a unique position in solid-state chemistry, characterized by its intricate stoichiometry and diverse structural arrangements observed across multiple reported configurations. Its electronic properties suggest potential utility in specialized optoelectronic or catalytic applications where tunable semiconducting behavior is required. Despite its structural diversity, the compound is identified as being thermodynamically above the hull, indicating a metastable nature that presents challenges for traditional bulk synthesis. This metastability is a key focus for researchers investigating phase stabilization and the kinetics of formation in complex transition metal oxynitrides.
Key Properties
