Abstract

Rb2Si(S2O7)3 crystallizes in the trigonal P-3 space group. The structure is three-dimensional. there are two inequivalent Rb1+ sites. In the first Rb1+ site, Rb1+ is bonded in a 9-coordinate geometry to nine O2- atoms. There are a spread of Rb–O bond distances ranging from 3.11–3.22 Å. In the second Rb1+ site, Rb1+ is bonded in a 9-coordinate geometry to nine O2- atoms. There are a spread of Rb–O bond distances ranging from 2.96–3.23 Å. Si4+ is bonded to six O2- atoms to form SiO6 octahedra that share corners with six SO4 tetrahedra. All Si–O bond lengths are 1.79 Å. There are two inequivalent S6+ sites. In the first S6+ site, S6+ is bonded to four O2- atoms to form SO4 tetrahedra that share a cornercorner with one SiO6 octahedra and a cornercorner with one SO4 tetrahedra. The corner-sharing octahedral tilt angles are 40°. There are a spread of S–O bond distances ranging from 1.43–1.67 Å. In the second S6+ site, S6+ is bonded to four O2- atoms to form SO4 tetrahedra that share a cornercorner with one SiO6 octahedra and a cornercorner with one SO4 tetrahedra. The corner-sharing octahedral tilt angles are 45°. There are a spread of S–O bondmore »« less
