Y2Mn2S2O5 crystallizes in the tetragonal I4/mmm space group. Y(1) is bonded in a 9-coordinate geometry to five equivalent S(1) and four equivalent O(2) atoms. Mn(1) is bonded in a 5-coordinate geometry to one S(1), one O(1), and four equivalent O(2) atoms. S(1) is bonded in a 6-coordinate geometry to five equivalent Y(1) and one Mn(1) atom. There are two inequivalent O sites. In the first O site, O(1) is bonded in a linear geometry to two equivalent Mn(1) atoms. In the second O site, O(2) is bonded to two equivalent Y(1) and two equivalent Mn(1) atoms to form a mixture of distorted corner and edge-sharing OY2Mn2 tetrahedra.
