We’re being asked to determine which of the tetrahedral hole and octahedral hole sites are occupied by Rb atoms if a compound has formula of Rb3C60 and C60 have a face-centered cubic arrangement.
Recall that the face-centered cubic lattice contains an atom in each of the face of the cube and an atom in each of the corners. It looks like this:
A compound with the formula Rb3C60 has been shown to demonstrate superconductivity below 30.0 K.
Given that the C60 molecules have a face-centered cubic arrangement, which of the tetrahedral and octahedral sites are occupied by Rb atoms?
