Acetylacetonate Formula Diagram (C5H8O2)Yttrium Acetylacetonate Hydrate is a Yttrium source that is soluble in organic solvents as an organometallic compound (also known as metalorganic, organo-inorganic and metallo-organic Acetylacetonate Packaging, Lab Quantitycompounds). The high purity acetylacetonate anion complexes by bonding each oxygen atom to the metallic cation to form a chelate ring; because of this property, acetylacetonates are commonly used in various catalysts and catalytic reagents for organic synthesis, including the fabrication of various shapes of carbon nanostructures (as demonstrated by a 2013 experiment by researchers at the Leibniz Institute for Solid State and Materials Research Dresden) via the use of chemical vapor deposition (CVD) and laser evaporation techniques. Yttrium Acetylacetonate is one of numerous organo-metallic compounds (also known as metalorganic, organo-inorganic and metallo-organic compounds) sold by American Elements under the trade name AE Organo-Metallics™. The numerous commercial applications for Yttrium include ceramics for crucibles for molten reactive metals, in florescent lighting phosphors, computer displays and automotive fuel consumption sensors. Additional technical, research and safety (MSDS) information is available as is a Reference Calculator for converting relevant units of measurement.

Related Products & Element Information

See more Yttrium products. Yttrium (atomic symbol: Y, atomic number: 39) is a Block D, Group 3, Period 5 element with an atomic weight of 88.90585. Yttrium Bohr ModelThe number of electrons in each of yttrium's shells is [2, 8, 18, 9, 2] and its electron configuration is [Kr] 4d1 5s2. The yttrium atom has a radius of 180 pm and a Van der Waals radius of 219 pm. Yttrium was discovered by Johann Gadolin in 1794 and first isolated by Carl Gustav Mosander in 1840. In its elemental form, Yttrium has a silvery white metallic appearance. Yttrium has the highest thermodynamic affinity for oxygen of any element. Elemental YttriumYttrium is not found in nature as a free element and is almost always found combined with the lanthanides in rare earth minerals. While not part of the rare earth series, it resembles the heavy rare earths which are sometimes referred to as the "yttrics" for this reason. Another unique characteristic derives from its ability to form crystals with useful properties. The name yttrium originated from a Swedish village near Vaxholm called Yttbery where it was discovered.
