Figure 2
The crystal structure of owyheeite viewed down [100]. Atoms are represented by gray (S), blue (predominant Pb), red (predominant Sb), green (Ag) and orange (putative Cu) spheres of arbitrary radius. Blue and orange backgrounds mark the two kinds of crystal-chemical rods according to the interpretation of Laufek et al. (2007). Light colors of the background indicates a translational component of a/2. The p-subscript in cp means that the axis is (slightly) out of plane, owing to the slightly obtuse angle β. The n[010] glide reflection planes are indicated by the usual dash-dotted lines. |
