The crystal structure described by DyEuCr4O12 crystallizes in the orthorhombic Amm2 space group. Dy(1) is bonded to two equivalent O(2), two equivalent O(3), four equivalent O(1), and four equivalent O(5) atoms to form distorted DyO12 cuboctahedra that share corners with four equivalent Dy(1)O12 cuboctahedra and faces with eight equivalent Cr(1)O6 octahedra. Eu(1) is bonded in a 12-coordinate geometry to two equivalent O(2), two equivalent O(3), four equivalent O(1), and four equivalent O(4) atoms. Cr(1) is bonded to one O(2), one O(3), one O(4), one O(5), and two equivalent O(1) atoms to form CrO6 octahedra that share corners with six equivalent Cr(1)O6 octahedra and faces with two equivalent Dy(1)O12 cuboctahedra. The corner-sharing octahedral tilt angles range from 12-19°. There are five inequivalent O sites. In the first O site, O(1) is bonded in a 2-coordinate geometry to one Dy(1), one Eu(1), and two equivalent Cr(1) atoms. In the second O site, O(2) is bonded in a 3-coordinate geometry to one Dy(1), one Eu(1), and two equivalent Cr(1) atoms. In the third O site, O(3) is bonded in a distorted rectangular see-saw-like geometry to one Dy(1), one Eu(1), and two equivalent Cr(1) atoms. In the fourth O site, O(4) is bonded in a 2-coordinate geometry to two equivalent Eu(1) and two equivalent Cr(1) atoms. In the fifth O site, O(5) is bonded in a 3-coordinate geometry to two equivalent Dy(1) and two equivalent Cr(1) atoms. is represented by the CIF card [CIF]
