Materials Data on Rb3MgNb5O15 by Materials Project
Abstract
Rb3MgNb5O15 crystallizes in the orthorhombic P2_12_12_1 space group. The structure is three-dimensional. there are three inequivalent Rb1+ sites. In the first Rb1+ site, Rb1+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of Rb–O bond distances ranging from 2.86–3.34 Å. In the second Rb1+ site, Rb1+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of Rb–O bond distances ranging from 2.93–3.31 Å. In the third Rb1+ site, Rb1+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of Rb–O bond distances ranging from 2.97–3.32 Å. Mg2+ is bonded in a 6-coordinate geometry to six O2- atoms. There are a spread of Mg–O bond distances ranging from 1.96–2.46 Å. There are five inequivalent Nb5+ sites. In the first Nb5+ site, Nb5+ is bonded in a 5-coordinate geometry to six O2- atoms. There are a spread of Nb–O bond distances ranging from 1.83–2.60 Å. In the second Nb5+ site, Nb5+ is bonded to six O2- atoms to form a mixture of distorted corner and edge-sharing NbO6 octahedra. The corner-sharing octahedral tilt angles are 29°. There are a spread of Nb–O bond distances ranging from 1.80–2.39more »
