The compound described by Dy2GeO5 crystallizes in the monoclinic C2/c space group. There are two inequivalent Dy sites. In the first Dy site, Dy(1) is bonded in a 7-coordinate geometry to one O(3), two equivalent O(2), two equivalent O(4), and two equivalent O(5) atoms. In the second Dy site, Dy(2) is bonded in a 6-coordinate geometry to one O(3), one O(5), two equivalent O(1), and two equivalent O(4) atoms. Ge(1) is bonded in a tetrahedral geometry to one O(1), one O(2), one O(3), and one O(5) atom. There are five inequivalent O sites. In the first O site, O(3) is bonded in a distorted trigonal planar geometry to one Dy(1), one Dy(2), and one Ge(1) atom. In the second O site, O(4) is bonded to two equivalent Dy(1) and two equivalent Dy(2) atoms to form edge-sharing ODy4 tetrahedra. In the third O site, O(5) is bonded in a 4-coordinate geometry to one Dy(2), two equivalent Dy(1), and one Ge(1) atom. In the fourth O site, O(1) is bonded in a trigonal non-coplanar geometry to two equivalent Dy(2) and one Ge(1) atom. In the fifth O site, O(2) is bonded in a 3-coordinate geometry to two equivalent Dy(1) and one Ge(1) atom. is represented by the CIF file [CIF]
