this structure, and the As atoms do not form a perfect octahedron. Together with the unit cell size and the assigned space group, the aforementioned parameters fully describe the crystal structure of the material. This structure is often referred to as the skutterudite structure. Applications Materials with a skutterudite structure are studied as a low cost thermoelectric material with low thermal conductivity. See also Thermoelectric materials#Skutterudite thermoelectrics.
