Materials Data on Nb2PbO6 by Materials Project
Abstract
PbNb2O6 crystallizes in the trigonal R3m space group. The structure is three-dimensional. Nb5+ is bonded to six O2- atoms to form NbO6 octahedra that share corners with four equivalent NbO6 octahedra, edges with two equivalent PbO12 cuboctahedra, and an edgeedge with one NbO6 octahedra. The corner-sharing octahedra tilt angles range from 24–41°. There are a spread of Nb–O bond distances ranging from 1.85–2.19 Å. There are three inequivalent Pb2+ sites. In the first Pb2+ site, Pb2+ is bonded to twelve O2- atoms to form PbO12 cuboctahedra that share edges with twelve equivalent NbO6 octahedra. There are a spread of Pb–O bond distances ranging from 2.76–3.06 Å. In the second Pb2+ site, Pb2+ is bonded in a 3-coordinate geometry to three equivalent O2- atoms. All Pb–O bond lengths are 2.33 Å. In the third Pb2+ site, Pb2+ is bonded in a 3-coordinate geometry to three equivalent O2- atoms. All Pb–O bond lengths are 2.32 Å. There are five inequivalent O2- sites. In the first O2- site, O2- is bonded in a bent 150 degrees geometry to two equivalent Nb5+ atoms. In the second O2- site, O2- is bonded in a distorted bent 150 degrees geometry to two equivalent Nb5+ and onemore »
