For 10 points, name this moleculer geometry which resembles an eight-faced solid.
The superconducting Chevrel phase adopts this geometry, whose stability complex for formation can be found form the Irving-Williams series. They can isomerize via a reaction that forces them through a C-sub-2v intermediate or a D-sub-3h intermediate. Besides undergoing the Ray-Dutt or Bailar twists, their ligands can be arranged facially or meridonally. Werner complexes exhibit this formation, whose orbitals can be divided into the t-sub-2g and e-sub-g sets due to crystal field splitting. One of their axes may elongate to break degeneracy in the classic Jahn-Teller effect, and this geometry occurs in sulfur hexafloride, molybdenum hexacarbonyl, or any complex with no lone pairs and six ligands according to VSEPR theory.
