Platinát

Platinát is a term that can refer to a salt or ester of platinic acid. Platinic acid itself is an unstable compound that is a theoretical precursor to many platinum-containing compounds. In inorganic chemistry, "platinát" typically denotes a complex anion where platinum is the central atom, often in a higher oxidation state such as +4. Examples of platinate anions include [PtCl6]2- (hexachloroplatinate) and [Pt(OH)6]2- (hexahydroxyplatinate). These complexes are often formed by platinum(IV) compounds.

Historically, the study of platinates has been important in understanding the coordination chemistry of platinum. The preparation and characterization of various platinate salts have contributed to the development of platinum-based drugs, such as cisplatin, which is a platinum(II) complex but its chemistry is related to the broader field of platinum coordination compounds. Some platinate compounds have also found applications as catalysts in chemical reactions due to the catalytic properties of platinum. The term can also, though less commonly, refer to an ester derived from platinic acid, where platinum is bonded to organic groups through oxygen. However, the anionic complex interpretation is far more prevalent in chemical literature.
