Each cation in a compound with the ZnS structure is surrounded by four anions at the corners of a tetrahedron. Each anion is surrounded by a tetrahedron of cations. The coordination number both of the cations and of the anions is four. The coordination geometry of both is tetrahedral.

Click on any cation or anion to highlight the coordination polyhedron. The underlined texts above link to definitions.

Some of the components of the cubes around ions in the drawing are located in adjacent unit cells.
