CaF Crystal Structure Unit Cell Model
SKU: 68761W
The calcium fluoride (fluorite) unit cell Indigo® 68761W molecular model shows Oh point group symmetry, face-centered cubic packing, and tetrahedral coordination of fluoride ions. Ideal for solid state chemistry, crystallography, mineralogy, and materials science courses.
The Indigo® 68761W model can build a calcium fluoride (CaF2) unit cell, an important structure in solid state chemistry and mineralogy. The unit cell belongs to the Oh point group and crystallographic space group Fm3m that exemplifies the full cubic symmetry of the face-centered cubic lattice. Calcium ions (Ca2+) form a face-centered cubic sublattice with fluoride ions (F-) at all eight tetrahedral interstitial sites within the unit cell. Each Ca2+ ion coordinates eight F- ions in a cubic arrangement, while each F- ion is surrounded tetrahedrally by four Ca2+ ions. This yields an 8:4 coordination geometry that reflects the 1:2 stoichiometry of CaF2. Fluorite's four directions of cleavage along the {111} planes is a direct consequence of its cubic symmetry.
Indigo Instruments has held inventory of genuine Cochranes of Oxford (Orbit) parts for 30+ years (See Skeletal (Orbit/Minit)) that are compatible with every molecular model we have sold since day 1. This level of quality may appear expensive but no parts support from other vendors costs even more.
