FeCr crystallizes in the orthorhombic Cmmm space group. Cr(1) is bonded in a 12-coordinate geometry to four equivalent Cr(1) and eight equivalent Fe(1) atoms. Fe(1) is bonded in a 12-coordinate geometry to eight equivalent Cr(1) and four equivalent Fe(1) atoms.
FeCr crystallizes in the orthorhombic Cmmm space group. Cr(1) is bonded in a 12-coordinate geometry to four equivalent Cr(1) and eight equivalent Fe(1) atoms. All Cr(1)-Cr(1) bond lengths are 2.43 Å. There are four shorter (2.49 Å) and four longer (2.79 Å) Cr(1)-Fe(1) bond lengths. Fe(1) is bonded in a 12-coordinate geometry to eight equivalent Cr(1) and four equivalent Fe(1) atoms. All Fe(1)-Fe(1) bond lengths are 2.43 Å.
