Antimony: Inorganic Chemistry

Abstract

This article covers the inorganic chemistry of the element antimony. Information on the occurrence, production, use, and properties of the element and of compounds with bonds between antimony and main group elements (except carbon) and transition metals are provided.

Antimonene: a tuneable post-graphene material for advanced applications in optoelectronics, catalysis, energy and biomedicine

“…An alternative method to obtain Sb is to directly reduce the stibnite with scrap iron, followed by a purification procedure with sodium nitrate and sodium carbonate. 22,23 Fig. 1 schematizes the production of elemental Sb from stibnite.…”

“…In this context, there are several studies reporting antimony hydrides (SbH 3 ), compounds with elements of group 13 or 14 (GaSb, Sb(SiMe 3 )), with other pnictogens such as N or P (Sb(NR 2 )), antimony chalcogens (Sb 2 O 3 , Sb 2 (SO 4 ) 3 , Sb 2 S 3 ), antimony halides (SbCl 3 , SbF 5 ) or antimonides with Sb 3− such as Li 3 Sb or Na 3 Sb, to name a few. 23 Although it appears mainly in inorganic compounds, Sb also has a rich organometallic chemistry. 31 After the synthesis of the first trialkyl antimony compounds in around 1850 – trimethyl- and triethylstibine – an incredible variety of organoantimony compounds have been reported to date, mainly in the oxidation states of (+3) and (+5).…”

A Third Generation Potentially Bifunctional Trithiol Chelate, Its nat,1XXSb(III) Complex, and Selective Chelation of Radioantimony (119Sb) from Its Sn Target

“…Clinical treatments for antimony and fellow pnictogen arsenic poisoning employ two chelators: meso-2,3-dimercaptosuccinic acid (DMSA) and 2,3-dimercaptopropane-1-sulfonic acid (DMPS) . Antimony is considered a large, , soft atom, , and similar to arsenic, antimony is thiophilic and forms complexes with thiol donor atoms. − The greatest barrier to medical application of 119 Sb is the lack of stable complexation with a bifunctional chelator that has the ability to chelate Sb and also covalently bind to a targeting moiety. The only reported chelation of radioantimony was a 117 Sb Potassium Antimonyl Tartrate (PAT) complex published in 1969 .…”
