metalorthovanadate
Metalorthovanadate refers to a class of inorganic chemical compounds with the general formula M3VO4, where M represents a metal cation. These compounds are salts derived from orthovanadic acid (H3VO4). The most common examples include sodium orthovanadate (Na3VO4) and potassium orthovanadate (K3VO4). The structure typically involves isolated VO43- tetrahedra coordinated to metal cations. The properties of metalorthovanadates vary significantly depending on the identity of the metal cation. For instance, alkali metal orthovanadates are generally soluble in water, whereas those of alkaline earth metals or transition metals are often insoluble. These compounds can be synthesized through various methods, including precipitation reactions or high-temperature solid-state reactions. Metalorthovanadates find applications in areas such as catalysis, pigments, and as precursors for the synthesis of other vanadium-containing materials. Some metalorthovanadates exhibit interesting magnetic or optical properties, making them subjects of ongoing research. The specific oxidation state of vanadium in these compounds is +5.
