Rhodium Acetylacetonate is a Rhodium source that is soluble in organic solvents. The high purity acetylacetonate anion complexes by bonding each oxygen atom to the metallic cation to form a chelate ring.Because of this property, Rhodium Acetylacetonate is commonly used in various catalysts and catalytic reagents for organic synthesis. It is generally immediately available in most volumes. Ultra high purity and high purity forms may be considered. Rhodium Acetylacetonate is one of numerous organo-metallic compounds sold by American Elements under the tradename AE Organo-Metallics™ for uses requiring non-aqueous solubility such as recent solar energy and water treatment applications. Similar results can sometimes also be achieved with Nanoparticles (also see Nanotechnology and Quantum Dots) and by thin film deposition. Note American Elements additionally supplies many materials as solutions. The numerous commercial applications for Rhodium include plating metal in jewelry production to enhance the whiteness of white gold.American Elements produces to many standard grades when applicable, including Mil Spec (military grade); ACS, Reagent and Technical Grade; Food, Agricultural and Pharmaceutical Grade; Optical Grade, USP and EP/BP (European Pharmacopoeia/British Pharmacopoeia)and follows applicable ASTM testing standards.Typical and custom packaging is available. Additional technical, research and safety (MSDS) information is available as is a Reference Calculator for converting relevant units of measurement.
Rhodium is a Block D, Group 9, Period 5 element. The number of electrons in each of Rhodium's shells is 2, 8, 18, 16, 1 and its electronic configuration is [Kr] 4d8 5s1. In its elemental form rhodium's CAS number is 7440-16-6. The rhodium atom has a radius of 134.5.pm and it's Van der Waals radius is 200.pm. Rhodium is not toxic. Rhodium is a member of the platinum group of metals. It has a higher melting point than platinum, but a lower density.
It is alloyed with platinum and palladium in electrodes for spark plugs, advanced laboratory equipment and in thermocouples. Rhodium compounds also have catalytic uses in automotive catalytic converters. Rhodium is used as a plating metal in jewelry production to enhance the whiteness of white gold. Rhodium is available as metal and compounds with purities from 99% to 99.999% (ACS grade to ultra-high purity); metals in the form of foil, sputtering target, and rod, and compounds as submicron and nanopowder. Rhodium was first discovered by William Wollaston in 1803. The name Rhodium, originates from the Greek word 'Rhodon' which means rose. See Rhodium research below.
