Abstract

(Nb2S2O11)8O2 crystallizes in the trigonal R-3 space group. The structure is three-dimensional and consists of three water molecules and one Nb2S2O11 framework. In the Nb2S2O11 framework, there are two inequivalent Nb sites. In the first Nb site, Nb is bonded to six O atoms to form NbO6 octahedra that share corners with three NbO6 octahedra and corners with three SO4 tetrahedra. The corner-sharing octahedral tilt angles are 8°. There are a spread of Nb–O bond distances ranging from 1.88–2.14 Å. In the second Nb site, Nb is bonded to six O atoms to form NbO6 octahedra that share corners with three equivalent NbO6 octahedra and corners with three equivalent SO4 tetrahedra. The corner-sharing octahedral tilt angles are 8°. There are three shorter (1.93 Å) and three longer (2.09 Å) Nb–O bond lengths. There are two inequivalent S sites. In the first S site, S is bonded to four O atoms to form SO4 tetrahedra that share corners with three NbO6 octahedra. The corner-sharing octahedra tilt angles range from 25–36°. There are a spread of S–O bond distances ranging from 1.42–1.52 Å. In the second S site, S is bonded to four O atoms to form SO4 tetrahedra that share cornersmore »« less
