Aluminium nitrate is a strong oxidizing agent. It is used in tanning leather, antiperspirants , corrosion inhibitors , extraction of uranium , petroleum refining , and as a nitrating agent. The nonahydrate and other hydrated aluminium nitrates have many applications.
Lewis structure of a water molecule. Lewis structures – also called Lewis dot formulas, Lewis dot structures, electron dot structures, or Lewis electron dot structures (LEDs) – are diagrams that show the bonding between atoms of a molecule, as well as the lone pairs of electrons that may exist in the molecule.
Aluminium nitride (Al N) is a solid nitride of aluminium. It has a high thermal conductivity of up to 321 W/(m·K) [ 5 ] and is an electrical insulator. Its wurtzite phase (w-AlN) has a band gap of ~6 eV at room temperature and has a potential application in optoelectronics operating at deep ultraviolet frequencies.
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.

As aluminium is a small atom relative to these chalcogens, these have four-coordinate tetrahedral aluminium with various polymorphs having structures related to wurtzite, with two-thirds of the possible metal sites occupied either in an orderly (α) or random (β) fashion; the sulfide also has a γ form related to γ-alumina, and an unusual ...
In contrast to boron, aluminium is a larger atom and easily accommodates four carbon ligands. The triorganoaluminium compounds are thus usually dimeric with a pair of bridging alkyl ligands, e.g., Al 2 (C 2 H 5) 4 (μ-C 2 H 5) 2. Thus, despite its common name of triethylaluminium, this compound contains two aluminium centres, and six ethyl groups.
The crystal structure of the compound [H(Et 2 O) 2][B(C 6 F 5) 4],. [8] H atoms are omitted from the image. Color code: red = O, yellow = F, gray = C. The neutral molecules that represent the parents to the non-coordinating anions are strong Lewis acids, e.g. boron trifluoride, BF 3 and phosphorus pentafluoride, PF 5.
When hydrated aluminium nitrate reacts with dinitrogen pentoxide it forms a nitronium salt: [NO 2] + [Al(NO 3) 4] −. [2]A way to make a tetranitratoaluminate salt of a cation is to treat the chloride of the cation and aluminium chloride with liquid dinitrogen tetroxide pure or dissolved in nitromethane.
