Hexaammineplatinum(IV) chloride
Hexaammineplatinum(IV) chloride is the name of an inorganic coordination compound with the chemical formula [Pt(NH3)6]Cl4. It is a platinum(IV) complex in which six ammonia (NH3) ligands are coordinated to a central platinum(IV) ion (Pt4+). The chloride ions (Cl-) serve as counter-ions to balance the positive charge of the complex.
This compound is a salt, typically appearing as a yellow or white crystalline solid. It is soluble in water, where the complex cation and chloride anions dissociate.
The systematic name for this compound, following IUPAC nomenclature, is hexaammineplatinum(IV) chloride. The prefix "hexa-" indicates the presence of six ammonia ligands. The Roman numeral "(IV)" indicates the oxidation state of the platinum atom.
Hexaammineplatinum(IV) chloride, like other platinum complexes, has been of interest in research contexts, particularly in the areas of coordination chemistry and materials science. The synthesis and characterization of such complexes contribute to the understanding of chemical bonding, electronic structure, and reactivity of transition metal compounds. It is not commonly used in large-scale industrial applications.
The preparation of hexaammineplatinum(IV) chloride typically involves the reaction of a suitable platinum(II) or platinum(IV) precursor with ammonia, followed by oxidation (if starting from a platinum(II) compound) and precipitation with chloride ions. The exact synthetic method depends on the availability of starting materials and desired purity.
