Enneasartorite

Enneasartorite is a very rare mineral[2] with formula Tl6Pb32As70S140. It belongs to sartorite homologous series.[1] It is related to other recently approved minerals of the sartorite series: hendekasartorite and heptasartorite.[3][4] All come from Lengenbach quarry in Switzerland, which is famous for thallium sulfosalts.[5] Enneasartorite is chemically similar to edenharterite and hutchinsonite.[6][7]
