mp-18905: FeO (cubic, Fm-3m, 225) - Materials Project
FeO is Halite, Rock Salt structured and crystallizes in the monoclinic C2/c space group. The structure is three-dimensional. Fe2+ is bonded to six equivalent O2- atoms to form a mixture of edge and corner-sharing FeO6 octahedra.
Iron(II) oxide - Wikipedia
Iron(II) oxide adopts the cubic, rock salt structure, where iron atoms are octahedrally coordinated by oxygen atoms and the oxygen atoms octahedrally coordinated by iron atoms. The non-stoichiometry occurs because of the ease of oxidation of Fe II to Fe III effectively replacing a small portion of Fe II with two-thirds their number of Fe III ...
