The material described by DyCrGeO5 crystallizes in the orthorhombic Pbam space group. Dy(1) is bonded in a 8-coordinate geometry to two equivalent O(3), two equivalent O(4), and four equivalent O(1) atoms. Cr(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form CrO6 octahedra that share corners with four equivalent Ge(1)O5 square pyramids and edges with two equivalent Cr(1)O6 octahedra. Ge(1) is bonded to one O(2), two equivalent O(1), and two equivalent O(4) atoms to form distorted GeO5 square pyramids that share corners with four equivalent Cr(1)O6 octahedra and  an edgeedge with one Ge(1)O5 square pyramid. The corner-sharing octahedral tilt angles range from 48-55°. There are four inequivalent O sites. In the first O site, O(1) is bonded in a 4-coordinate geometry to two equivalent Dy(1), one Cr(1), and one Ge(1) atom. In the second O site, O(2) is bonded in a distorted trigonal planar geometry to two equivalent Cr(1) and one Ge(1) atom. In the third O site, O(3) is bonded to two equivalent Dy(1) and two equivalent Cr(1) atoms to form distorted ODy2Cr2 trigonal pyramids that share corners with four equivalent O(4)Dy2Ge2 tetrahedra, corners with two equivalent O(3)Dy2Cr2 trigonal pyramids, and  an edgeedge with one O(3)Dy2Cr2 trigonal pyramid. In the fourth O site, O(4) is bonded to two equivalent Dy(1) and two equivalent Ge(1) atoms to form distorted ODy2Ge2 tetrahedra that share corners with four equivalent O(3)Dy2Cr2 trigonal pyramids and edges with two equivalent O(4)Dy2Ge2 tetrahedra. is represented by the CIF file [CIF]
