Lengenbachite
Lengenbachite is a rare sulfosalt mineral with the chemical formula silver tetra-copper diodec-lead dodeca-arsenic tritriaconta-sulfide. It belongs to the Strunz classification 2.HF.30 and crystallizes in the monoclinic system. The mineral is typically found in a dark gray to black color with a metallic luster. It has a relatively low hardness on the Mohs scale, making it soft and easily scratched. Lengenbachite is part of the sulfosalt mineral group, characterized by complex structures combining sulfur with metal atoms. It is notable for its unique chemical composition and is primarily of interest to mineral collectors and researchers due to its rarity and complex structure.
