Materials Data on Rb3InO3 by Materials Project
Rb3InO3 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. there are three inequivalent Rb1+ sites. In the first Rb1+ site, Rb1+ is bonded to five O2- atoms to form distorted RbO5 trigonal bipyramids that share corners with four equivalent InO4 tetrahedra, corners with two equivalent RbO5 trigonal bipyramids, an edgeedge with one InO4 tetrahedra, and an edgeedge with one RbO5 trigonal bipyramid. There are a spread of Rb–O bond distances ranging from 2.80–3.17 Å. In the second Rb1+ site, Rb1+ is bonded in a 5-coordinate geometry to five O2- atoms. There are a spread of Rb–O bond distances ranging from 2.82–3.23 Å. In the third Rb1+ site, Rb1+ is bonded in a 3-coordinate geometry to five O2- atoms. There are a spread of Rb–O bond distances ranging from 2.71–3.43 Å. In3+ is bonded to four O2- atoms to form InO4 tetrahedra that share corners with four equivalent RbO5 trigonal bipyramids, an edgeedge with one InO4 tetrahedra, and an edgeedge with one RbO5 trigonal bipyramid. There are a spread of In–O bond distances ranging from 2.08–2.16 Å. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded in a 1-coordinate geometry to six Rb1+ and one In3+ atom. In the second O2- site, O2- is bonded in a 5-coordinate geometry to three Rb1+ and two equivalent In3+ atoms. In the third O2- site, O2- is bonded in a 1-coordinate geometry to six Rb1+ and one In3+ atom.
