Na2Te2
Na2Te2 is the chemical formula for disodium ditelluride. It is an inorganic compound belonging to the family of alkali metal tellurides. Disodium ditelluride is known to exist as a solid compound. Its structure typically involves sodium cations and ditelluride anions (Te2^2-). The ditelluride anion is characterized by a direct bond between two tellurium atoms. This compound can be synthesized through various methods, often involving the reaction of sodium with tellurium at elevated temperatures. For example, melting sodium and tellurium together in stoichiometric ratios can yield Na2Te2. The compound is generally sensitive to air and moisture, and can decompose in the presence of water, potentially releasing hydrogen telluride. Na2Te2 has been investigated for its electrochemical properties and potential applications in areas such as batteries and thermoelectric materials, although its practical use is limited due to its reactivity and the cost of tellurium. It is considered a binary salt.
