The compound described by MgDy2Cr2O8 crystallizes in the monoclinic C2 space group. Mg(1) is bonded in a 4-coordinate geometry to two equivalent O(2), two equivalent O(3), and two equivalent O(4) atoms. There are two inequivalent Dy sites. In the first Dy site, Dy(1) is bonded in a 8-coordinate geometry to two equivalent O(1), two equivalent O(2), two equivalent O(3), and two equivalent O(4) atoms. In the second Dy site, Dy(2) is bonded in a 8-coordinate geometry to two equivalent O(1), two equivalent O(2), two equivalent O(3), and two equivalent O(4) atoms. There are two inequivalent Cr sites. In the first Cr site, Cr(1) is bonded in a distorted trigonal pyramidal geometry to two equivalent O(2) and two equivalent O(3) atoms. In the second Cr site, Cr(2) is bonded in a tetrahedral geometry to two equivalent O(1) and two equivalent O(4) atoms. There are four inequivalent O sites. In the first O site, O(1) is bonded in a 3-coordinate geometry to one Dy(1), one Dy(2), and one Cr(2) atom. In the second O site, O(2) is bonded in a 4-coordinate geometry to one Mg(1), one Dy(1), one Dy(2), and one Cr(1) atom. In the third O site, O(3) is bonded in a distorted see-saw-like geometry to one Mg(1), one Dy(1), one Dy(2), and one Cr(1) atom. In the fourth O site, O(4) is bonded in a 4-coordinate geometry to one Mg(1), one Dy(1), one Dy(2), and one Cr(2) atom. is represented by the CIF file [CIF]
