MgY2Mn2S2O5 crystallizes in the orthorhombic Immm space group. Mg(1) is bonded in a square co-planar geometry to two equivalent O(2) and two equivalent O(3) atoms. Y(1) is bonded in a 9-coordinate geometry to five equivalent S(1), two equivalent O(1), and two equivalent O(2) atoms. Mn(1) is bonded to one S(1), one O(3), two equivalent O(1), and two equivalent O(2) atoms to form distorted corner-sharing MnSO5 octahedra. The corner-sharing octahedral tilt angles range from 0-18°. S(1) is bonded in a 6-coordinate geometry to five equivalent Y(1) and one Mn(1) atom. There are three inequivalent O sites. In the first O site, O(1) is bonded in a see-saw-like geometry to two equivalent Y(1) and two equivalent Mn(1) atoms. In the second O site, O(2) is bonded to one Mg(1), two equivalent Y(1), and two equivalent Mn(1) atoms to form corner-sharing OY2MgMn2 trigonal bipyramids. In the third O site, O(3) is bonded in a square co-planar geometry to two equivalent Mg(1) and two equivalent Mn(1) atoms.
