The compound described by Cd3GeO6 crystallizes in the orthorhombic Pmn2_1 space group. There are two inequivalent Cd sites. In the first Cd site, Cd(1) is bonded to one O(1), one O(3), two equivalent O(2), and two equivalent O(4) atoms to form CdO6 octahedra that share corners with four equivalent Cd(2)O6 octahedra, corners with two equivalent Ge(1)O4 tetrahedra, edges with four equivalent Cd(2)O6 octahedra, and  an edgeedge with one Ge(1)O4 tetrahedra. The corner-sharing octahedral tilt angles range from 59-64°. In the second Cd site, Cd(2) is bonded to one O(1), one O(3), two equivalent O(2), and two equivalent O(4) atoms to form distorted CdO6 octahedra that share corners with two equivalent Cd(1)O6 octahedra, corners with four equivalent Cd(2)O6 octahedra, corners with two equivalent Ge(1)O4 tetrahedra,  an edgeedge with one Cd(2)O6 octahedra, edges with two equivalent Cd(1)O6 octahedra, and  an edgeedge with one Ge(1)O4 tetrahedra. The corner-sharing octahedral tilt angles range from 51-64°. Ge(1) is bonded to one O(1), one O(3), and two equivalent O(4) atoms to form GeO4 tetrahedra that share corners with two equivalent Cd(1)O6 octahedra, corners with four equivalent Cd(2)O6 octahedra,  an edgeedge with one Cd(1)O6 octahedra, and edges with two equivalent Cd(2)O6 octahedra. The corner-sharing octahedral tilt angles range from 6-63°. There are four inequivalent O sites. In the first O site, O(1) is bonded in a distorted rectangular see-saw-like geometry to one Cd(1), two equivalent Cd(2), and one Ge(1) atom. In the second O site, O(2) is bonded in a trigonal planar geometry to one Cd(1) and two equivalent Cd(2) atoms. In the third O site, O(3) is bonded in a distorted tetrahedral geometry to one Cd(1), two equivalent Cd(2), and one Ge(1) atom. In the fourth O site, O(4) is bonded in a distorted rectangular see-saw-like geometry to one Cd(1), two equivalent Cd(2), and one Ge(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
