Iridium Trichloride （ IrCl₃ ， CAS:10025-83-9 ） , also known as Iridium(III) Chloride or IrCl₃ , is a dark brown to black crystalline solid that plays a vital role in inorganic chemistry and catalysis. It is a highly stable iridium compound known for its ability to form numerous coordination complexes and serve as a key precursor in iridium-based catalysts and materials. Because of its thermal stability , chemical inertness , and versatile reactivity , Iridium Trichloride is widely used in industrial catalysis , materials science , and electrochemical research . Chemica Chemical formula IrCl₃ Iridium Trichloride often exists in anhydrous or hydrated forms (IrCl₃·xH₂O). In hydrated forms, iridium is surrounded by a mix of chloride and water ligands, making it highly reactive for complex formation. Key Applications of Iridium Trichloride 1. Catalyst Precursor IrCl₃ is one of the most important starting materials for iridium catalysts . It...
