Abstract

CdGeO3 is Esseneite-derived structured and crystallizes in the tetragonal I4_1/a space group. The structure is three-dimensional. there are three inequivalent Cd2+ sites. In the first Cd2+ site, Cd2+ is bonded to six O2- atoms to form CdO6 octahedra that share corners with six GeO4 tetrahedra. There are a spread of Cd–O bond distances ranging from 2.28–2.34 Å. In the second Cd2+ site, Cd2+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of Cd–O bond distances ranging from 2.36–2.65 Å. In the third Cd2+ site, Cd2+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of Cd–O bond distances ranging from 2.28–2.81 Å. There are four inequivalent Ge4+ sites. In the first Ge4+ site, Ge4+ is bonded to four O2- atoms to form GeO4 tetrahedra that share corners with two equivalent CdO6 octahedra and corners with two equivalent GeO6 octahedra. The corner-sharing octahedra tilt angles range from 47–57°. There are a spread of Ge–O bond distances ranging from 1.76–1.84 Å. In the second Ge4+ site, Ge4+ is bonded to four equivalent O2- atoms to form corner-sharing GeO4 tetrahedra. The corner-sharing octahedral tilt angles are 42°. All Ge–O bond lengths aremore »« less
