| has gloss | eng: A metaphosphate ion is an oxyanion that has the empirical formula PO3-. The structure of a metaphosphate ion can be described as being made up of PO4 structural units in which each unit shares two corners with another unit. This can come about in two ways. * Formation of a ring, as in trimetaphosphate, illustrated. * Formation of an infinite chain , with the same structure as in ammonium metavanadate |
