The material described by FeO is Moissanite-4H structured and crystallizes in the hexagonal P6_3mc space group. There are two inequivalent Fe sites. In the first Fe site, Fe(1) is bonded to one O(1) and three equivalent O(2) atoms to form corner-sharing FeO4 tetrahedra. In the second Fe site, Fe(2) is bonded to one O(2) and three equivalent O(1) atoms to form corner-sharing FeO4 tetrahedra. There are two inequivalent O sites. In the first O site, O(1) is bonded to one Fe(1) and three equivalent Fe(2) atoms to form corner-sharing OFe4 tetrahedra. In the second O site, O(2) is bonded to one Fe(2) and three equivalent Fe(1) atoms to form corner-sharing OFe4 tetrahedra. is represented by the CIF card [CIF]
