Wulfenite, PbMoO4. The stereoview shows well-formed wulfenite crystals on a matrix. The view can be compared to that in the Smithsonian Gem collection

The molecular structure of Wulfenite is shown in the following two figures. The first is the contents of the unit cell.

The following figure shows a stereographic space-filling representation of 18 unit cells of Wulfenite. Red spheres are oxygen atoms, purple molydbenum, and yellow represent lead.

.

The final figure shows the 18 cells using polyhedra (purple are the MoO4 polyhedra, yellow are the PbO7 polyhedra).
