The structure described by Fe1Cr2 is Cubic Laves structured and crystallizes in the cubic Fd-3m space group. Cr(1) is bonded to six equivalent Cr(1) and six equivalent Fe(1) atoms to form a mixture of face, corner, and edge-sharing CrCr6Fe6 cuboctahedra. Fe(1) is bonded in a 16-coordinate geometry to twelve equivalent Cr(1) and four equivalent Fe(1) atoms. is represented by the CIF card [CIF]
