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]}
