description: TiPb(S2O7)3 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. Ti4+ is bonded to six O2- atoms to form TiO6 octahedra that share corners with six SO4 tetrahedra. There are a spread of Ti–O bond distances ranging from 1.93–1.99 Å. Pb2+ is bonded in a 9-coordinate geometry to nine O2- atoms. There are a spread of Pb–O bond distances ranging from 2.60–3.02 Å. There are six 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 TiO6 octahedra and a cornercorner with one SO4 tetrahedra. The corner-sharing octahedral tilt angles are 42°. There are a spread of S–O bond distances ranging from 1.44–1.64 Å. In the second S6+ site, S6+ is bonded to four O2- atoms to form SO4 tetrahedra that share a cornercorner with one TiO6 octahedra and a cornercorner with one SO4 tetrahedra.
