The material described by SrDy2CuO5 crystallizes in the orthorhombic Pnma space group. Sr(1) is bonded in a 9-coordinate geometry to two equivalent O(3), three equivalent O(1), and four equivalent O(2) atoms. There are two inequivalent Dy sites. In the first Dy site, Dy(1) is bonded to one O(1), two equivalent O(2), and four equivalent O(3) atoms to form distorted DyO7 pentagonal bipyramids that share corners with five equivalent Cu(1)O5 square pyramids, edges with two equivalent Dy(1)O7 pentagonal bipyramids, and  an edgeedge with one Cu(1)O5 square pyramid. In the second Dy site, Dy(2) is bonded in a 7-coordinate geometry to one O(1), two equivalent O(3), and four equivalent O(2) atoms. Cu(1) is bonded to one O(1), two equivalent O(2), and two equivalent O(3) atoms to form CuO5 square pyramids that share corners with five equivalent Dy(1)O7 pentagonal bipyramids and  an edgeedge with one Dy(1)O7 pentagonal bipyramid. There are three inequivalent O sites. In the first O site, O(1) is bonded to three equivalent Sr(1), one Dy(1), one Dy(2), and one Cu(1) atom to form a mixture of edge and corner-sharing OSr3Dy2Cu octahedra. The corner-sharing octahedral tilt angles are 4°. In the second O site, O(2) is bonded in a 6-coordinate geometry to two equivalent Sr(1), one Dy(1), two equivalent Dy(2), and one Cu(1) atom. In the third O site, O(3) is bonded in a 4-coordinate geometry to one Sr(1), one Dy(2), two equivalent Dy(1), and one Cu(1) atom. is represented by the CIF file [CIF]
