description: RbV3Cd4O12 crystallizes in the monoclinic Cc space group. The structure is three-dimensional. Rb1+ is bonded in a 10-coordinate geometry to ten O2- atoms. There are a spread of Rb–O bond distances ranging from 2.80–3.44 Å. There are three inequivalent V5+ sites. In the first V5+ site, V5+ is bonded to four O2- atoms to form VO4 tetrahedra that share corners with four CdO6 octahedra and corners with two equivalent CdO6 pentagonal pyramids. The corner-sharing octahedra tilt angles range from 53–61°. There are a spread of V–O bond distances ranging from 1.74–1.78 Å. In the second V5+ site, V5+ is bonded to four O2- atoms to form VO4 tetrahedra that share corners with four CdO6 octahedra and corners with two equivalent CdO6 pentagonal pyramids. The corner-sharing octahedra tilt angles range from 40–66°. There are a spread of V–O bond distances ranging from 1.72–1.78 Å. In the third V5+ site, V5+ is bonded to four O2- atoms to form VO4 tetrahedra that share corners with four CdO6 octahedra and corners with two equivalent CdO6 pentagonal pyramids. The corner-sharing octahedra tilt angles range from 39–65°. There are a spread of V–O bond distances ranging from 1.71–1.81 Å. There are four inequivalent Cd2+ sites. In the first Cd2+ site, Cd2+ is bonded to six O2- atoms to form distorted CdO6 pentagonal pyramids that share corners with six VO4 tetrahedra and edges with two CdO6 octahedra. There are a spread of Cd–O bond distances ranging from 2.36–2.41 Å. In the second Cd2+ site, Cd2+ is bonded to six O2- atoms to form CdO6 octahedra that share corners with six VO4 tetrahedra, an edgeedge with one CdO6 octahedra, and an edgeedge with one CdO6 pentagonal pyramid. There are a spread of Cd–O bond distances ranging from 2.27–2.33 Å. In the third Cd2+ site, Cd2+ is bonded to six O2- atoms to form CdO6 octahedra that share corners with six VO4 tetrahedra, an edgeedge with one CdO6 octahedra, and an edgeedge with one CdO6 pentagonal pyramid.
