CdGeO3 crystallizes in the monoclinic Cc space group. The structure is three-dimensional. Cd2+ is bonded to five O2- atoms to form corner-sharing CdO5 square pyramids. There are a spread of Cd–O bond distances ranging from 2.24–2.37 Å. Ge4+ is bonded in a distorted T-shaped geometry to three O2- atoms. There are a spread of Ge–O bond distances ranging from 1.76–2.19 Å. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted rectangular see-saw-like geometry to one Cd2+, one Ge4+, and two equivalent O2- atoms. Both O–O bond lengths are 1.78 Å. In the second O2- site, O2- is bonded in a distorted trigonal planar geometry to two equivalent Cd2+ and one Ge4+ atom. In the third O2- site, O2- is bonded in a trigonal non-coplanar geometry to two equivalent Cd2+ and one Ge4+ atom.
