• Physical properties: Erbium is a soft, malleable metal with a silvery metallic luster that only tarnishes (oxidizes)slightly in air. It is one of the rare-earths of the yttrium subgroup of the lanthanide series.Its melting point is 1,529°C, its boiling point is 2,868°C, and its density is 9.07g/cm3.
• Uses: Erbium has application in glass coloring, as an amplifier in fiber optics, and in lasers for medical and dental use. It is commonly used as a photographic filter, and because of its resilience it is useful as a metallurgical additive. The Erbium ion has a very narrow absorption band coloring erbium salts pink. It is therefore used in eyeware and decorative glassware. It can neutralize discoloring impurities such as ferric ions and produce a neutral gray shade. It is used in a variety of glass products for this purpose. Lasers based on Er:YAG are ideally suited for surgical applications because of its ability to deliver energy without thermal build-up in tissue. Erbium Metal, is mainly metallurgical uses. Added to vanadium, for example, Erbium lowers hardness and improves workability. There are also a few applications for nuclear industry. Erbium Metal can be further processed to various shapes of ingots, pieces, wires, foils, slabs, rods, discs and powder. Erbium has limited commercial use, but it is used as an alloy metal for vanadium to makeit easier to work and to form spring steel. The oxide of erbium is pink, which is used to colorglass and to make lasers that will operate at normal room temperatures. It has limited use ascontrol rods in nuclear fission reactors. Erbium foil used in Physical Vapor Deposition (PVD) processes, including thermal and electron-beam (e-beam) evaporation, for the preparation of thin films. It is used as an alloying element with titanium and is also used to produce infra-red absorbing glass.

Heteroleptic [M(CH₂C₆H₅) ₂(I)(THF)₃] complexes (M = y or Er): Remarkably stable precursors to yttrium and erbium T-shaped carbenes

10.1021/om9007949

The research focuses on the synthesis and properties of heteroleptic dibenzyl yttrium and erbium iodides [Ln(Bn)2(I)(THF)3] (Ln = Y (1), Er (2); Bn = CH2C6H5), which are notable for their thermal stability and resistance to ligand scrambling. These complexes serve as precursors to yttrium and erbium T-shaped carbenes. The study demonstrates the synthetic utility of 1 and 2 by reacting them with H2BIPM to produce phosphorus-stabilized yttrium and erbium carbenes [Ln(BIPM)(I)(THF)2] (Ln = Y (3); Er (4); BIPM = {C(PPh2NSiMe3)}2-). The research involves the use of various reagents, including [Y(I)3(THF)3.5]21 and [K(Bn)]20 for the preparation of 1, and analogous reagents for the synthesis of 2. The compounds were characterized using X-ray crystallography, multinuclear NMR spectroscopy, FTIR spectroscopy, room-temperature Evans method solution magnetic moments, and CHN microanalyses. The study also includes DFT calculations to analyze the bonding and electronic structure of the synthesized compounds.
