Materials Data on CdGeO3 by Materials Project
CdGeO3 crystallizes in the monoclinic Cc space group. The structure is three-dimensional. Cd2+ is bonded in a 5-coordinate geometry to five O2- atoms. There are a spread of Cd–O bond distances ranging from 2.08–2.46 Å. Ge4+ is bonded to five O2- atoms to form distorted edge-sharing GeO5 trigonal bipyramids. There are a spread of Ge–O bond distances ranging from 1.72–1.93 Å. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded to two equivalent Cd2+ and two equivalent Ge4+ atoms to form a mixture of distorted edge and corner-sharing OCd2Ge2 tetrahedra. In the second O2- site, O2- is bonded to two equivalent Cd2+ and two equivalent Ge4+ atoms to form a mixture of distorted edge and corner-sharing OCd2Ge2 tetrahedra. In the third O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Cd2+ and one Ge4+ atom.
