Homonuclear triatomic molecules contain three of the same kind of atom. That molecule will be an allotrope of that element. Ozone, O 3 is an example of a triatomic molecule with all atoms the same. Triatomic hydrogen, H 3, is unstable and breaks up spontaneously. H 3 +, the trihydrogen cation is stable by itself and is symmetric.
Organozinc compounds were among the first organometallic compounds made. They are less reactive than many other analogous organometallic reagents, such as Grignard and organolithium reagents . In 1848 Edward Frankland prepared the first organozinc compound, diethylzinc , by heating ethyl iodide in the presence of zinc metal. [ 5 ]
Organozinc compounds contain zinc—carbon covalent bonds. Diethylzinc ((C 2 H 5) 2 Zn) was first reported in 1848. It was made by reaction of zinc and ethyl iodide and is the first compound known to contain a metal—carbon sigma bond. [25] For a long time it was a mystery why copper(II) did not form an analogous compound.
Organozinc compounds are those that contain zinc–carbon covalent bonds. Diethylzinc ((C 2 H 5) 2 Zn) is a reagent in synthetic chemistry. It was first reported in 1848 from the reaction of zinc and ethyl iodide, and was the first compound known to contain a metal–carbon sigma bond. [70]
A steel bottle containing MgCp 2 (magnesium bis-cyclopentadienyl), which, like several other organometallic compounds, is pyrophoric in air.. Organometallic compounds are distinguished by the prefix "organo-" (e.g., organopalladium compounds), and include all compounds which contain a bond between a metal atom and a carbon atom of an organyl group.

Electrochemically oxidized iron (rust) An iron oxide is a chemical compound composed of iron and oxygen. Several iron oxides are recognized. Often they are non-stoichiometric. Ferric oxyhydroxides are a related class of compounds, perhaps the best known of which is rust. [1]
Tetramethylammonium ozonide, which can be made by a metathesis reaction with caesium ozonide in liquid ammonia, is stable up to 348 K (75 °C): [4] CsO 3 + [(CH 3) 4 N][O 2] → CsO 2 + [(CH 3) 4 N][O 3] Alkaline earth metal ozonide compounds have also become known. For instance, magnesium ozonide complexes have been isolated in a low ...
Most of the organic compounds that contain oxygen are not made by direct action of oxygen. Organic compounds important in industry and commerce are made by direct oxidation of a precursor include: [6] Ethylene oxide (used to make the antifreeze ethylene glycol) is obtained by direct oxidation of ethylene: C 2 H 4 + ½ O 2 + catalyst ...
