About: Bismuth polycations

An Entity of Type: Thing, from Named Graph: http://dbpedia.org, within Data Space: dbpedia.org

Bismuth polycations are polyatomic ions of the formula Bin+x. They were originally observed in solutions of bismuth metal in molten bismuth chloride. It has since been found that these clusters are present in the solid state, particularly in salts where germanium tetrachloride or tetrachloroaluminate serve as the counteranions, but also in amorphous phases such as glasses and gels. Bismuth endows materials with a variety of interesting optical properties that can be tuned by changing the supporting material. Commonly-reported structures include the trigonal bipyramidal Bi3+5 cluster, the octahedral Bi2+6 cluster, the square antiprismatic Bi2+8 cluster, and the tricapped trigonal prismatic Bi5+9 cluster.
