The bismuthide ion is Bi3− but the term is often used to describe less reduced forms of bismuth.
Bismuthides are compounds of bismuth with more electropositive elements. A wide variety are known.
The stoichiometry of bismuthides ranges from lithium bismuthide (Li3Bi), which can be viewed as the Li+ salt of Bi3-. The corresponding sodium and potassium derivatives are also known. They all prepared by heating the elements.[1]
In terms of Bi-rich phases, examples are LiBi, KBi2, CaBi3, which exhibit strong Bi-Bi bonding.[2] Some are intermetallic compounds, containing partially metallic and partially ionic bonds. The majority of bismuthides adopt efficient packing arrangements and become densely packed structures, which is a characteristic of intermetallic compounds.
