The Calcium ions are surrounded by eight neighboring fluoride ions, while the fluoride ions are surrounded by a tetrahedron of four calcium ions. Note that in the resulting structure every alternate cube of fluoride ions has no calcium ion in its center. The (111) plane is the natural cleavage plane of the crystal, in this picture, it is

Calcium fluoride (CaF2 or fluorite) is grown by vacuum Stockbarger technique in diameters of up to about 250mm. Crystal for infrared use is often grown using naturally mined fluorite to reduce costs. It will not have the best transmission in the UV and VUV and can have absorption bands at 300nm due to impurities.
