  2. Nitric oxide - Wikipedia

    en.wikipedia.org/wiki/Nitric_oxide

    Nitric oxide reacts with transition metals to give complexes called metal nitrosyls. The most common bonding mode of nitric oxide is the terminal linear type (M−NO). [6] Alternatively, nitric oxide can serve as a one-electron pseudohalide. In such complexes, the M−N−O group is characterized by an angle between 120° and 140°.

    These complexes are isoelectronic and, incidentally, both obey the 18-electron rule. The formal description of nitric oxide as NO + does not match certain measureable and calculated properties. In an alternative description, nitric oxide serves as a 3-electron donor, and the metal-nitrogen interaction is a triple bond. linear and bent M-NO bonds

  4. Nitrosation and nitrosylation - Wikipedia

    en.wikipedia.org/wiki/Nitrosation_and_nitrosylation

    Nitrosation and nitrosylation. Nitrosylation results in a molecule "R" adducted with the group N=O. Nitrosation and nitrosylation are two names for the process of converting organic compounds or metal complexes [1] into nitroso derivatives, i.e., compounds containing the R−NO functionality. The synonymy arises because the R-NO functionality ...

  5. Nitroso - Wikipedia

    en.wikipedia.org/wiki/Nitroso

    Nitrosyls are non-organic compounds containing the NO group, for example directly bound to the metal via the N atom, giving a metal–NO moiety. Alternatively, a nonmetal example is the common reagent nitrosyl chloride (Cl−N=O). Nitric oxide is a stable radical, having an unpaired electron. Reduction of nitric oxide gives the nitrosyl anion ...

  6. Nitric oxide synthase - Wikipedia

    en.wikipedia.org/wiki/Nitric_oxide_synthase

    Nitric oxide synthases (EC 1.14.13.39) (NOSs) are a family of enzymes catalyzing the production of nitric oxide (NO) from L-arginine. NO is an important cellular signaling molecule. It helps modulate vascular tone , insulin secretion, airway tone, and peristalsis , and is involved in angiogenesis and neural development.

  7. Pi backbonding - Wikipedia

    en.wikipedia.org/wiki/Pi_backbonding

    Pi backbonding. In chemistry, π backbonding is a π-bonding interaction between a filled (or half filled) orbital of a transition metal atom and a vacant orbital on an adjacent ion or molecule. [1][2] In this type of interaction, electrons from the metal are used to bond to the ligand, which dissipates excess negative charge and stabilizes the ...

  8. Nitrosonium - Wikipedia

    en.wikipedia.org/wiki/Nitrosonium

    It can be viewed as nitric oxide with one electron removed. This ion is usually obtained as the following salts: NOClO 4, NOSO 4 H (nitrosylsulfuric acid, more descriptively written ONSO 3 OH) and NOBF 4. The ClO − 4 and BF − 4 salts are slightly soluble in acetonitrile CH 3 CN.

  9. Group 9 element - Wikipedia

    en.wikipedia.org/wiki/Group_9_element

    synthetic element. Group 9, by modern IUPAC numbering, [1] is a group (column) of chemical elements in the d-block of the periodic table. Members of Group 9 include cobalt (Co), rhodium (Rh), iridium (Ir) and meitnerium (Mt). [2] These elements are among the rarest of the transition metals. [3] Like other groups, the members of this family show ...
