Tris(isopropylcyclopentadienyl)praseodymium(III) 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. Tris(isopropylcyclopentadienyl)praseodymium(III) is generally immediately available in most volumes, including bulk quantities. American Elements can produce materials to custom specifications by request, in addition to custom compositions for commercial and research applications and new proprietary technologies. American Elements also casts any of the rare earth metals and most other advanced materials into rod, bar or plate form, as well as numerous other machined shapes and in the form of solutions and organometallic compounds. Ultra high purity and high purity forms also include metal powder, submicron powder and nanomaterials, targets for thin film deposition, and pellets for chemical vapor deposition (CVD) and physical vapor deposition (PVD) applications. 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, as is additional technical and safety (MSDS) data. Please contact us for information on lead time and pricing above.

Praseodymium (Pr) atomic and molecular weight, atomic number and elemental symbol Praseodymium (atomic symbol: Pr, atomic number: 59) is a Block F, Group 3, Period 6 element with an atomic weight of 140.90765. Praseodymium Bohr Model The number of electrons in each of praseodymium's shells is 2, 8, 18, 21, 8, 2 and its electron configuration is [Xe]4f3 6s2. The praseodymium atom has a radius of 182 pm and a Van der Waals radius of 239 pm. Praseodymium resembles the typical trivalent rare earths, however, it will exhibit a +4 state when stabilized in a zirconia host. Elemental Praseodymium Unlike other rare-earth metals, which show antiferromagnetic and / or ferromagnetic ordering at low temperatures, praseodymium is paramagnetic at any temperature above 1 K. Praseodymium is found in the minerals monazite and bastnasite. Praseodymium was discovered by Carl Auer von Welsbach in 1885. The origin of the element name comes from the Greek words prasios didymos, meaning green twin.
