Abstract

A redox, substitution and self-assembly reaction offers a novel dysprosium selenoarsenate(iii) with As(3+) [Dy2(tepa)2(?2-OH)2Cl2]3[As3Se6]2 (1, tepa = tetraethylenepentamine), which provides the first example of chair conformation ring [As3Se6](3-) combined with lanthanide complexes as counterions. 1 exhibits a photocurrent response and slow magnetic relaxation behavior.

Dysprosium Bohr ModelThe number of electrons in each of dysprosium's shells is [2, 8, 18, 28, 8, 2] and its electron configuration is [Xe]4f10 6s2. The dysprosium atom has an atomic radius of 178 pm and a Van der Waals radius of 229 pm. Dysprosium was first discovered by Paul Emile Lecoq de Boisbaudran in 1886. In its elemental form, dysprosium has a silvery-white appearance. Elemental Dysprosium PictureIt is a member of the lanthanide or rare earth series of elements and, along with holmium, has the highest magnetic strength of all other elements on the periodic table, especially at low temperatures. Dysprosium is found in various minerals including bastnäsite, blomstrandine, euxenite, fergusonite, gadolinite, monazite, polycrase and xenotime. It is not found in nature as a free element. The element name originates from the Greek word dysprositos, meaning hard to get at.

Selenium

Selenium Bohr ModelSee more Selenium products. Selenium (atomic symbol: Se, atomic number: 34) is a Block P, Group 16, Period 4 element with an atomic radius of 78.96. The number of electrons in each of Selenium's shells is 2, 8, 18, 6 and its electron configuration is [Ar] 3d10 4s2 4p4. The selenium atom has a radius of 120 pm and a Van der Waals radius of 190 pm. Selenium is a non-metal with several allotropes: a black, vitreous form with an irregular crystal structure three red-colored forms with monoclinic crystal structures and a gray form with a hexagonal crystal structure, the most stable and dense form of the element. Elemental SeleniumOne of the most common uses for selenium is in glass production the red tint that it lends to glass neutralizes green or yellow tints from impurities in the glass materials. Selenium was discovered and first isolated by Jöns Jakob Berzelius and Johann Gottlieb Gahn in 1817. The origin of the name Selenium comes from the Greek word "Selênê," meaning moon.
