Tris(tetramethylcyclopentadienyl)gadolinium(III) is one of numerous organo-metallic compounds (also known as metalorganic, organo-inorganic and metallo-organic 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. Tris(tetramethylcyclopentadienyl)gadolinium(III) is generally immediately available in most volumes. High purity, submicron and nanopowder forms may be considered. Additional technical, research and safety information is available.
Gadolinium is a Block F, Group 3, Period 6 element. The number of electrons in each of Gadolinium's shells is 2, 8, 18, 25, 9, 2 and its electronic configuration is [Xe] 4f7 5d1 6s2. In its elemental form gadolinium's CAS number is 7440-54-2. The gadolinium atom has a radius of 178.7.pm and it's Van der Waals radius is unknown. Gadolinium is very toxic. Gadolinium is utilized for both its high magnetic moment (7.94µB) and in phosphors and scintillator material. When complexed with EDTA ligands, it is used as an injectable contrast agent for patients undergoing magnetic resonance imaging. With its high magnetic moment, gadolinium can reduce relaxation times and thereby enhance signal intensity. The extra stable half-full 4f electron shell with no low lying energy levels creates applications as an inert phosphor host. Gadolinium can therefore act as hosts for x-ray cassettes and in scintillator materials for computer tomography. Gadolinium 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. Gadolinium was first discovered by Jean de Marignac in 1880. The element is named after the Finnish chemist and geologist Johan Gadolin. See Gadolinium research below.
