The crystal structure described by FeS is Modderite structured and crystallizes in the orthorhombic Pnma space group. Fe(1) is bonded to six equivalent S(1) atoms to form a mixture of distorted edge, corner, and face-sharing FeS6 octahedra. The corner-sharing octahedral tilt angles range from 45-58°. S(1) is bonded in a 6-coordinate geometry to six equivalent Fe(1) atoms. is represented by the CIF file [CIF]
