Antimonide bromide

Short description: Chemical compounds

Antimonide bromides or bromide antimonides are compounds containing anions composed of bromide (Br−) and antimonide (Sb3−). They can be considered as mixed anion compounds. They are in the category of pnictidehalides. Related compounds include the antimonide chlorides, antimonide iodides, arsenide chlorides, arsenide bromides, arsenide iodides, phosphide chlorides, phosphide bromides, and phosphide iodides.[1] The bromoantimonates have antimony in positive oxidation states.

The antimony can be linked into chains, in which case it has a formal oxidation state of −1. Alternately it can be in pairs as Sb2, with an oxidation state of −2 for each atom.[2]

Many of these compounds are clathrates, whereby there are two interpenetrating structures that are only weakly bound to each other by van der Waals force.
