About Cannizzarite
Stanislao Cannizzaro
Formula:
Pb48Bi56S132
S may be replaced by minor Se (or Se may even be essential). The structure solution (Topa et al., 2010) gave Pb48Bi56(S124Se8)sum132. This can be simplified to Pb6Bi7(S,Se)16.5.
Previously given as Pb8Bi10S23.
Previously given as Pb8Bi10S23.

Monoclinic
Name:
Named by F. Zambonini, O. de Fiore, and G. Carobbi in 1924 in honor of Stanislao Cannizzaro (13 July 1826, Palermo, Sicily, Italy – 10 May 1910, Rome, Italy), chemist. He is best known for the Cannizzaro reaction and his work on atomic weights.
