Iridium

Description:

Iridium is a dense, silvery-white transition metal belonging to the platinum group of elements, known for its remarkable resistance to corrosion and oxidation. It has a high melting point and is one of the most corrosion-resistant metals, making it valuable in various industrial applications. Iridium is typically found in nature as an alloy with other platinum group metals and is often extracted from nickel and copper ores. Its atomic number is 77, and it exhibits a variety of oxidation states, with +3 and +4 being the most common in compounds. Iridium is used in high-temperature applications, electrical contacts, and spark plugs, as well as in the production of certain types of catalysts. Additionally, due to its rarity and unique properties, iridium is also utilized in specialized scientific instruments and in the field of jewelry. Its high density and hardness contribute to its durability, while its chemical inertness makes it suitable for use in harsh environments.

Controlled Product

CAS: 7439-88-5

Iridium is a transition metal that belongs to the group of platinum-group metals. It has the ability to catalyze chemical reactions, especially in organic chemistry. Iridium can be used as a catalyst for the metathesis reaction, which involves the exchange of an organic group between two molecules. Iridium also has a redox potential that is higher than those of many other metals and this makes it useful for reducing other metals from their salts. The ligands are often coordinated to iridium through dative bonds with four ligands, forming a square planar geometry. This coordination geometry is not found in most organometallic complexes, which usually have octahedral or tetrahedral geometries. The complex is obtained by reacting iridium with picolinic acid and the reaction solution is then analyzed using X-ray diffraction to determine its structure.
