The Cesium Chloride Structue

Ball-and Stick Model The cesium chloride structure is not based on close-packing. In this structure, the cesium ions (white spheres) form a simple cubic lattice and the chloride ions (green spheres) occupy the cubic holes. The cesium and chloride ions are of roughly the same radius, so the structure could alternately be viewed as a simple cubic lattice of chloride ions with the cesium ions in the cubic holes. This illustration shows a ball-and-stick model of the halite strutcure.

Eight Unit Cells This model shows eight unit cells (2 x 2 x 2) of the cesium chloride structure. The cesium chloride structure has a coordination number of 8:8; that is each ion is surrounded by eight of the other type.
