Pincer ligands are chelating agents that binds tightly to three adjacent coplanar sites in a meridional configuration.

In chemistry, a transition metal pincer complex is a type of coordination complex with a pincer ligand. Evaporation to dryness and burning under hydrogen gas gives pure iridium. 3D image of an iridium diphosphine pincer complex. Dissolution of the oxide in regia (a mixture of hydrochloric acid, HCl, and nitric acid, HNO 3) gives a solution containing pure (NH 4) 3IrCl 6. Iridium Metallic Color is an exquisite choice in the automotive paint spectrum, drawing inspiration from the rarity and brilliance of the precious metal iridium. It is commonly used in the automotive industry to give vehicles a modern and sleek appearance. The residue contains iridium oxide, IrO 2. Iridium metallic color is a shade of gray with a reflective sheen. Indium is found on planets orbiting blue stars, and can be placed in a Refiner to create purified Chromatic Metal for use in the manufacture of advanced technologies. Such stellar material ends up forming deposits in the crust of local planets. The residue is melted with Na 2O 2 and extracted into water to remove ruthenium and osmium salts. A chromatic metal, generated by fusion in the heart of a star. The insoluble residue contains the iridium. The residue is melted with sodium bisulphate (NaHSO 4) and the resulting mixture extracted with water to give a solution containing rhodium sulphate, Rh 2(SO 4) 3. The vanadium-based terephthalate analogs of MIL-68 have been obtained with gallium and indium (network composition: M(OH)(O2CC6H4CO2), M Ga or In) by using a solvothermal synthesis technique using N,N-dimethylformamide as a solvent (10 and 48 h, for Ga and In, respectively, at 100 ☌). Preliminary treatment of the ore or base metal byproduct is required to remove silver, gold, palladium, and platinum. The extraction is complex because of the other metals present and only worthwhile since iridium is useful as a specialist metal and is the basis of some catalysts in industry. Sometimes extraction of the precious metals such as iridium, rhodium, platinum and palladium is the main focus of a partiular industrial operation while in other cases it is a byproduct. The industrial extraction of iridium is complex as the metal occurs in ores mixed with other metals such as rhodium, palladium, silver, platinum, and gold. It has nine valence electrons that can occur in the oxidation states +1, +3, and +4. By integrating these two technologies, we are able to produce high-purity, precision. As a member of the platinum family of periodic table elements, iridium is characterized by a high density and hardness. Worthy of special mention is the fact that Furuya Metal has manufacturing technology for the melting and processing of iridium powder that is produced by iridium mines, as well as technology to produce high-purity iridium powder, mainly through recycling. In Earth’s crust, this precious metal occurs in scarce amounts.

Isolation: it would not normally be necessary to make a sample of iridium in the laboratory as the metal is available, at a price, commercially. Iridium is a chemical element with atomic number 77 in the periodic table.
