Routhierite, Tl(Cu,Ag)(Hg,Zn)₂(As,Sb)₂S₆

Synopsis: The crystal structure of the mineral routhierite, Tl(Cu,Ag)(Hg,Zn)₂(As,Sb)₂S₆, was solved and refined for the first time, and consists of (Cu,Ag)S₄ and (Hg,Zn)S₄ tetrahedra, which share corners to form a framework with channels parallel to [001]. These channels contain TlS₆ and (As,Sb)S₃ polyhedra that share corners and edges with the tetrahedra.

Formula: Tl(Cu,Ag)(Hg,Zn)₂(As,Sb)₂S₆
