The crystal structure described by DyFe10Cr2 crystallizes in the orthorhombic Immm space group. Dy(1) is bonded in a 20-coordinate geometry to two equivalent Cr(1), two equivalent Fe(4), four equivalent Fe(1), four equivalent Fe(2), and eight equivalent Fe(3) atoms. Cr(1) is bonded in a 14-coordinate geometry to one Dy(1), one Cr(1), two equivalent Fe(1), two equivalent Fe(2), four equivalent Fe(3), and four equivalent Fe(4) atoms. There are four inequivalent Fe sites. In the first Fe site, Fe(1) is bonded in a 12-coordinate geometry to two equivalent Dy(1), two equivalent Cr(1), two equivalent Fe(2), two equivalent Fe(4), and four equivalent Fe(3) atoms. In the second Fe site, Fe(2) is bonded in a 12-coordinate geometry to two equivalent Dy(1), two equivalent Cr(1), two equivalent Fe(1), two equivalent Fe(4), and four equivalent Fe(3) atoms. In the third Fe site, Fe(3) is bonded to two equivalent Dy(1), two equivalent Cr(1), two equivalent Fe(1), two equivalent Fe(2), two equivalent Fe(3), and two equivalent Fe(4) atoms to form a mixture of edge, face, and corner-sharing FeDy2Cr2Fe8 cuboctahedra. In the fourth Fe site, Fe(4) is bonded in a 14-coordinate geometry to one Dy(1), four equivalent Cr(1), one Fe(4), two equivalent Fe(1), two equivalent Fe(2), and four equivalent Fe(3) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
