Abstract

NaSrNb2O6 crystallizes in the orthorhombic Cmmm space group. The structure is three-dimensional. Na1+ is bonded to twelve O2- atoms to form distorted NaO12 cuboctahedra that share corners with four equivalent NaO12 cuboctahedra, corners with eight equivalent SrO12 cuboctahedra, faces with two equivalent NaO12 cuboctahedra, faces with four equivalent SrO12 cuboctahedra, and faces with eight equivalent NbO6 octahedra. There are a spread of Na–O bond distances ranging from 2.74–3.05 Å. Sr2+ is bonded to twelve O2- atoms to form SrO12 cuboctahedra that share corners with four equivalent SrO12 cuboctahedra, corners with eight equivalent NaO12 cuboctahedra, faces with two equivalent SrO12 cuboctahedra, faces with four equivalent NaO12 cuboctahedra, and faces with eight equivalent NbO6 octahedra. There are a spread of Sr–O bond distances ranging from 2.69–2.99 Å. Nb+4.50+ is bonded to six O2- atoms to form NbO6 octahedra that share corners with six equivalent NbO6 octahedra, faces with four equivalent NaO12 cuboctahedra, and faces with four equivalent SrO12 cuboctahedra. The corner-sharing octahedra tilt angles range from 0–15°. There are two shorter (2.02 Å) and four longer (2.03 Å) Nb–O bond lengths. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded in a 2-coordinate geometry to two equivalentmore »« less
