α-Calcium nitride adopts an anti-bixbyite structure, similar to Mn 2 O 3, except that the positions of the ions are reversed: calcium (Ca 2+) take the oxide (O 2−) positions and nitride ions (N 3−) the manganese (Mn 3+). In this structure, Ca 2+ occupies tetrahedral sites, and the nitride centres occupy two different types of octahedral ...
Calcium nitrite is an inorganic compound with the chemical formula Ca(NO 2) 2. In this compound, as in all nitrites, nitrogen is in a +3 oxidation state. It has many applications such as antifreeze, rust inhibitor of steel and wash heavy oil. [1]
[1] [2] [3] Introduced by Gilbert N. Lewis in his 1916 article The Atom and the Molecule, a Lewis structure can be drawn for any covalently bonded molecule, as well as coordination compounds. [ 4 ] Lewis structures extend the concept of the electron dot diagram by adding lines between atoms to represent shared pairs in a chemical bond.
The fertilizer grade (15.5-0-0 + 19% Ca) is popular in the greenhouse and hydroponics trades; it contains ammonium nitrate and water, as the "double salt" 5Ca(NO 3) 2 ·NH 4 NO 3 ·10H 2 O. This is called calcium ammonium nitrate and often the name calcium nitrate prill is used as it always comes in a prilled (granular) form.
3 → NO 3 + O 2. This reaction can be performed also in the solid phase or water solutions, by irradiating frozen gas mixtures, flash photolysis and radiolysis of nitrate salts and nitric acid, and several other methods. [1] Nitrogen trioxide is a product of the photolysis of dinitrogen pentoxide N 2 O 5, chlorine nitrate ClONO 2, and ...

In 1935, professor George H. Cady was first to synthesize fluorine nitrate and has since maintained a long and controversial history. In 1937, American chemist and biochemist Linus Pauling and one of his first graduate students, Lawrence O. Brockway, utilized electron diffraction intensities to determine the structure of the oxygen and fluorine bond perpendicular to the NO2 plane to be a non ...
Being the conjugate base of a strong acid (nitric acid, pK a = -1.4), nitrate has modest Lewis basicity.Two coordination modes are common: unidentate and bidentate.Often, bidentate nitrate, denoted κ 2-NO 3, is bound unsymmetrically in the sense that one M-O distance is clearly bonding and the other is more weakly interacting.
