Abstract

K2Sn(S2O7)3 crystallizes in the trigonal P-3 space group. The structure is three-dimensional. there are two inequivalent K1+ sites. In the first K1+ site, K1+ is bonded in a 9-coordinate geometry to nine O2- atoms. There are a spread of K–O bond distances ranging from 2.85–3.11 Å. In the second K1+ site, K1+ is bonded in a 6-coordinate geometry to six O2- atoms. There are three shorter (2.84 Å) and three longer (2.87 Å) K–O bond lengths. Sn4+ is bonded to six O2- atoms to form SnO6 octahedra that share corners with six SO4 tetrahedra. There are three shorter (2.07 Å) and three longer (2.08 Å) Sn–O bond lengths. 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 SnO6 octahedra and a cornercorner with one SO4 tetrahedra. The corner-sharing octahedral tilt angles are 44°. There are a spread of S–O bond distances ranging from 1.43–1.66 Å. In the second S6+ site, S6+ is bonded to four O2- atoms to form SO4 tetrahedra that share a cornercorner with one SnO6 octahedra and a cornercorner with one SO4 tetrahedra.
