Oxoanion

特許 係属中 An oxyanion or oxoanion is a chemical compound with the generic formula AxOyz− (where A represents a chemical element and O represents an oxygen atom). Oxoanions are formed by a large majority of the chemical elements.[1] The formulae of simple oxoanions are determined by the octet rule. The structures of condensed oxoanions can be rationalized in terms of AOn polyhedral units with sharing of corners or edges between polyhedra.
