Materials Data on Nb2SnO6 by Materials Project
SnNb2O6 crystallizes in the monoclinic C2/c space group. The structure is three-dimensional. Nb5+ is bonded to six O2- atoms to form a mixture of distorted edge and corner-sharing NbO6 octahedra. The corner-sharing octahedra tilt angles range from 29–56°. There are a spread of Nb–O bond distances ranging from 1.86–2.25 Å. Sn2+ is bonded in a distorted rectangular see-saw-like geometry to four equivalent O2- atoms. There are two shorter (2.20 Å) and two longer (2.40 Å) Sn–O bond lengths. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted trigonal planar geometry to three equivalent Nb5+ atoms. In the second O2- site, O2- is bonded in a bent 150 degrees geometry to two equivalent Nb5+ atoms. In the third O2- site, O2- is bonded in a 3-coordinate geometry to one Nb5+ and two equivalent Sn2+ atoms.
