Enneasartorite

Enneasartorite is a very rare mineral^[3] with formula Tl₆Pb₃₂As₇₀S₁₄₀. It belongs to sartorite homologous series.^[2] It is related to other recently approved minerals of the sartorite series: hendekasartorite and heptasartorite.^[4][5] All come from Lengenbach quarry in Switzerland, which is famous for thallium sulfosalts.^[6] Enneasartorite is chemically similar to edenharterite and hutchinsonite.^[7][8]
