Ph 5 Sb + HX → PhH + Ph 4 SbX Ph 5 Sb + X 2 → PhX + Ph 4 SbX For example, pentaphenylantimony reacts with dicarboxylic acids in solution, by substituting a phenyl group with the acid hydrogen.
Pentamethylantimony can be made by reacting Sb(CH 3) 3 Br 2 with two equivalents of methyl lithium. [3] Another production route is to convert trimethylstibine to the trimethyl antimony dichloride, and then replace the chlorine with methyl groups with methyl lithium. [2] Sb(CH 3) 3 + Cl 2 → Sb(CH 3) 3 Cl 2 Sb(CH 3) 3 Cl 2 + 2LiCH 3 → Sb(CH ...
Ph 3 Sb + Cl 2 → Ph 3 SbCl 2 Ph 3 SbCl 2 + 2 PhLi → Ph 5 Sb. Like their heavier congeners, the organobismuth compounds, stiboranes form onium compounds and ate complexes. Asymmetric compounds can also be obtained through the stibonium ion: R 5 Sb + X 2 → [R 4 Sb] + [X] [R 4 Sb] + [X] + R'MgX → R 4 R'Sb. Stibonium halides (R 4 SbX) tend ...
The antimony electrode has been investigated for its ability to function as a pH electrode. [1] The electrode is made of elemental antimony. The electrochemical process can be formulated as Sb 2 O 3 (s) + 6 H + + 6 e − ⇌ 2Sb(s) + 3H 2 O. The oxide, Sb 2 O 3, is present on the surface of the electrode. Although this electrode does not give ...
NBO of Sb(C 6 F 5) 3-P(O)Ph 3 adduct describing donor–acceptor interaction between lp(O) and σ*(Sb-C 6 F 5). [7]σ*(Sb–X), where X describes substituents on antimony, contributes to the Lewis acidity of antimony compounds in two ways: donor–acceptor orbital interaction and electrostatic interaction.

When heated to 700 °C (1,290 °F), the yellow hydrated pentoxide converts to an anhydrous white solid with the formula Sb 6 O 13, containing both antimony(III) and antimony(V). Heating to 900 °C (1,650 °F) produces a white, insoluble powder of Sb 2 O 4 in both α and β forms.
Fluoroantimonic acid is a mixture of hydrogen fluoride and antimony pentafluoride, containing various cations and anions (the simplest being H 2 F + and Sb F − 6).This mixture is a superacid that, in terms of corrosiveness, is trillions of times stronger than pure sulfuric acid when measured by its Hammett acidity function.
