Abstract

Li4Sr3Nb6O20 crystallizes in the orthorhombic Amm2 space group. The structure is three-dimensional. Li1+ is bonded in a 6-coordinate geometry to six O2- atoms. There are a spread of Li–O bond distances ranging from 2.07–2.74 Å. There are three inequivalent Sr2+ sites. In the first Sr2+ site, Sr2+ is bonded to twelve O2- atoms to form distorted SrO12 cuboctahedra that share corners with eight SrO12 cuboctahedra, a faceface with one SrO12 cuboctahedra, and faces with eight NbO6 octahedra. There are a spread of Sr–O bond distances ranging from 2.63–3.05 Å. In the second Sr2+ site, Sr2+ is bonded to twelve O2- atoms to form SrO12 cuboctahedra that share corners with four equivalent SrO12 cuboctahedra, faces with five SrO12 cuboctahedra, and faces with eight NbO6 octahedra. There are a spread of Sr–O bond distances ranging from 2.76–2.83 Å. In the third Sr2+ site, Sr2+ is bonded to twelve O2- atoms to form SrO12 cuboctahedra that share corners with eight SrO12 cuboctahedra, faces with four equivalent SrO12 cuboctahedra, and faces with eight NbO6 octahedra. There are four shorter (2.77 Å) and eight longer (2.83 Å) Sr–O bond lengths. There are five inequivalent Nb5+ sites. In the first Nb5+ site, Nb5+ is bonded tomore »« less
