  2. Nitrite - Wikipedia

    en.wikipedia.org/wiki/Nitrite

    The nitrite ion has a symmetrical structure (C 2v symmetry), with both N–O bonds having equal length and a bond angle of about 115°. In valence bond theory , it is described as a resonance hybrid with equal contributions from two canonical forms that are mirror images of each other.

  3. Azide - Wikipedia

    en.wikipedia.org/wiki/Azide

    In chemistry, azide (/ ˈ eɪ z aɪ d /, AY-zyd) is a linear, polyatomic anion with the formula N − 3 and structure − N=N + =N −. It is the conjugate base of hydrazoic acid HN 3. Organic azides are organic compounds with the formula RN 3, containing the azide functional group. [1] The dominant application of azides is as a propellant in ...

  4. Molecular symmetry - Wikipedia

    en.wikipedia.org/wiki/Molecular_symmetry

    Symmetry elements of formaldehyde. C 2 is a two-fold rotation axis. σ v and σ v ' are two non-equivalent reflection planes.. In chemistry, molecular symmetry describes the symmetry present in molecules and the classification of these molecules according to their symmetry.

  5. Transition metal nitrite complex - Wikipedia

    en.wikipedia.org/wiki/Transition_metal_nitrite...

    The copper-containing enzyme nitrite reductase (CuNIR) catalyzes the 1-electron reduction of nitrite to nitric oxide. The proposed mechanism entails the protonation of a κ 2O,O -NO 2 -Cu(I) complex. This protonation induces cleavage of an N–O bond, giving a HO–Cu–ON center, which features a nitric oxide ligand O-bonded to Cu(II) (an ...

  6. Nitrate nitrite - Wikipedia

    en.wikipedia.org/wiki/Nitrate_nitrite

    A nitrate nitrite, or nitrite nitrate, is a coordination complex or other chemical compound that contains both nitrite (NO − 2) and nitrate (NO − 3) anions. They are mixed-anion compounds, and they are mixed-valence compounds. Some have third anions. Many nitrite nitrate compounds are coordination complexes of cobalt.

  7. Tetrahedral molecular geometry - Wikipedia

    en.wikipedia.org/wiki/Tetrahedral_molecular_geometry

    In a tetrahedral molecular geometry, a central atom is located at the center with four substituents that are located at the corners of a tetrahedron.The bond angles are arccos(− ⁠ 1 / 3 ⁠) = 109.4712206...° ≈ 109.5° when all four substituents are the same, as in methane (CH 4) [1] [2] as well as its heavier analogues.

  8. Square pyramidal molecular geometry - Wikipedia

    en.wikipedia.org/wiki/Square_pyramidal_molecular...

    Structure of xenon oxytetrafluoride, an example of a molecule with the square pyramidal coordination geometry. Square pyramidal geometry describes the shape of certain chemical compounds with the formula ML 5 where L is a ligand. If the ligand atoms were connected, the resulting shape would be that of a pyramid with a square base.

  9. Nitrogen compounds - Wikipedia

    en.wikipedia.org/wiki/Nitrogen_compounds

    Nitrogen bonds to almost all the elements in the periodic table except the first three noble gases, helium, neon, and argon, and some of the very short-lived elements after bismuth, creating an immense variety of binary compounds with varying properties and applications. [3]
