Figure 2
The crystal structure of routhierite, showing the linking of (Cu,Ag)S4 and (Hg,Zn)S4 tetrahedra (in dark green and red, respectively, in the electronic version of the paper), which share corners to form a framework with channels hosting Tl and (As,Sb) atoms. (In the electronic version of the paper, blue, light-green and yellow spheres indicate Tl, As and S atoms, respectively.) The unit cell is outlined. |
