Hendekasartorite is a very rare thallium sulfosalt mineral[3] with formula Tl2Pb48As82S172. It is one of recently approved new members of sartorite homologous series,[2] by enneasartorite and heptasartorite.[4][5][3] All new members come from Lengenbach quarry in Switzerland, prolific in terms of thallium sulfosalt minerals.[6] Hendekasartorite is chemically similar to edenharterite and hutchinsonite.[7][8]
