Abstract

NaNb14O36 crystallizes in the orthorhombic Immm space group. The structure is three-dimensional. Na is bonded in a square co-planar geometry to four equivalent O atoms. All Na–O bond lengths are 2.55 Å. There are five inequivalent Nb sites. In the first Nb site, Nb is bonded in a 6-coordinate geometry to six O atoms. There are a spread of Nb–O bond distances ranging from 1.80–2.40 Å. In the second Nb site, Nb is bonded to six O atoms to form a mixture of distorted corner and edge-sharing NbO6 octahedra. The corner-sharing octahedra tilt angles range from 6–31°. There are a spread of Nb–O bond distances ranging from 1.84–2.29 Å. In the third Nb site, Nb is bonded to six O atoms to form corner-sharing NbO6 octahedra. The corner-sharing octahedra tilt angles range from 7–16°. There are a spread of Nb–O bond distances ranging from 1.92–2.16 Å. In the fourth Nb site, Nb is bonded in a 6-coordinate geometry to six O atoms. There are a spread of Nb–O bond distances ranging from 1.82–2.37 Å. In the fifth Nb site, Nb is bonded to six O atoms to form corner-sharing NbO6 octahedra. The corner-sharing octahedra tilt angles range from 6–13°. Theremore »« less
