The material structure described by FeO is Halite, Rock Salt structured and crystallizes in the tetragonal I4/mmm space group. Fe(1) is bonded to six equivalent O(1) atoms to form a mixture of corner and edge-sharing FeO6 octahedra. The corner-sharing octahedra are not tilted. O(1) is bonded to six equivalent Fe(1) atoms to form a mixture of corner and edge-sharing OFe6 octahedra. The corner-sharing octahedra are not tilted. is represented by the CIF card [CIF]
