oxidearsenates

Oxidearsenates are a class of inorganic compounds that contain the oxidearsenate anion, which has the general formula [AsO3]3-. This anion is characterized by a central arsenic atom bonded to three oxygen atoms, often with a negative charge distributed across these atoms. In oxidearsenates, this anion is typically combined with one or more metal cations. These compounds are related to both oxides and arsenates, reflecting the presence of oxygen and arsenic in their structure. The precise arrangement of atoms and the nature of the metal cations can lead to a variety of structural types and properties. Some oxidearsenates may exhibit properties relevant to materials science or geochemistry, depending on their specific composition and crystal structure. Their stability and reactivity are influenced by the oxidation state of arsenic, which is typically +3 in the [AsO3]3- anion, and the characteristics of the associated metal ions. Research into oxidearsenates may explore their synthesis, structural characterization, and potential applications, though they are less commonly discussed than simpler arsenates or oxides.
