  2. Transition metal carbonate and bicarbonate complexes

    en.wikipedia.org/wiki/Transition_metal_carbonate...

    The latter is consistent with the pK a ’s of carbonic acid: pK 1 = 6.77 and pK 2 = 9.93. To a single metal ion, carbonate is observed to bind in both unidentate (κ 1-) and bidentate (κ 2-) fashions. [5] In the covalent bond classification method, κ 1-carbonate is anX ligand and κ 2-carbonate is an X 2 ligand.

  3. Carbonation - Wikipedia

    en.wikipedia.org/wiki/Carbonation

    In chemistry, the term is sometimes used in place of carboxylation, which refers to the formation of carboxylic acids. In inorganic chemistry and geology, carbonation is common. Metal hydroxides (MOH) and metal oxides (M'O) react with CO 2 to give bicarbonates and carbonates: MOH + CO 2 → M(HCO 3) M'O + CO 2 → M'CO 3

  4. Transition metal carboxylate complex - Wikipedia

    en.wikipedia.org/wiki/Transition_metal_carboxyl...

    Attempts to prepare some carboxylate complexes, especially for electrophilic metals, often gives oxo derivatives. Examples include the oxo-acetates of Fe(III), Mn(III), and Cr(III). Pyrolysis of metal carboxylates affords acid anhydrides and the metal oxide. This reaction explains the formation of basic zinc acetate from anhydrous zinc diacetate.

  5. Metallacarboxylic acid - Wikipedia

    en.wikipedia.org/wiki/Metallacarboxylic_acid

    An illustrative synthesis is the reaction of a cationic iron carbonyl with a stoichiometric amount of base: [2] [(C 5 H 5)(CO) 2 FeCO]BF 4 + NaOH → [(C 5 H 5)(CO) 2 FeCO 2 H + NaBF 4. When applied to simple metal carbonyls, this kind of conversion is sometimes called the Hieber base reaction. Decarboxylation of the resulting anion gives the ...

  6. Reactivity series - Wikipedia

    en.wikipedia.org/wiki/Reactivity_series

    Metals in the middle of the reactivity series, such as iron, will react with acids such as sulfuric acid (but not water at normal temperatures) to give hydrogen and a metal salt, such as iron(II) sulfate: Fe (s) + H 2 SO 4 (l) → FeSO 4 (aq) + H 2 (g) There is some ambiguity at the borderlines between the groups.

  7. Kolbe electrolysis - Wikipedia

    en.wikipedia.org/wiki/Kolbe_electrolysis

    As an example, electrolysis of acetic acid yields ethane and carbon dioxide: CH 3 COOH → CH 3 COO − → CH 3 COO· → CH 3 · + CO 2 2CH 3 · → CH 3 CH 3. Another example is the synthesis of 2,7-dimethyl-2,7-dinitrooctane from 4-methyl-4-nitrovaleric acid: [3] The Kolbe reaction has also been occasionally used in cross-coupling reactions.

  8. Gallium compounds - Wikipedia

    en.wikipedia.org/wiki/Gallium_compounds

    Reacting a mixture of alkali metal carbonates and Ga 2 O 3 with H 2 S leads to the formation of thiogallates containing the [Ga 2 S 4] 2− anion. Strong acids decompose these salts, releasing H 2 S in the process. [7]: 104–105 The mercury salt, HgGa 2 S 4, can be used as a phosphor. [9]

  9. Transition metal nitrate complex - Wikipedia

    en.wikipedia.org/wiki/Transition_metal_nitrate...

    Many metals, metal halides, and metal carbonyls undergo similar reactions, but the product formulas can be deceptive. For example from chromium one obtains Cr(NO 3) 3 (N 2 O 4) 2, which was shown to be the salt (NO +) 2 [Cr(NO 3) 5] 2-. [15] Nitrogen oxides readily interconvert between various forms, some of which may act as completing ligands.
