Disordered Metal Atoms Sites of FeRu2(CO)12

The disordered metal atom sites shown above illustrate a possible pathway for the rotational motion of the metal atoms by 180o in the lattice. The atoms coloured blue trace out the path followed by the iron atom. This motion involves a considerable out-of-plane displacements for the Ru atoms in the intermediate 60o and 120o positions.
