Title: Materials Data on Ti2Fe3Bi3Pb2O15 by Materials Project

Abstract

Ti2Fe3Pb2Bi3O15 crystallizes in the orthorhombic Cmm2 space group. The structure is three-dimensional. Ti4+ is bonded to five O2- atoms to form distorted TiO5 trigonal bipyramids that share corners with two equivalent TiO5 trigonal bipyramids and corners with two equivalent FeO5 trigonal bipyramids. There are a spread of Ti–O bond distances ranging from 1.76–2.01 Å. There are two inequivalent Fe3+ sites. In the first Fe3+ site, Fe3+ is bonded to five O2- atoms to form distorted FeO5 trigonal bipyramids that share corners with two equivalent TiO5 trigonal bipyramids. There are a spread of Fe–O bond distances ranging from 1.85–2.03 Å. In the second Fe3+ site, Fe3+ is bonded in a 5-coordinate geometry to five O2- atoms. There is one shorter (1.84 Å) and four longer (2.02 Å) Fe–O bond length. Pb2+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of Pb–O bond distances ranging from 2.44–3.02 Å. There are two inequivalent Bi3+ sites. In the first Bi3+ site, Bi3+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of Bi–O bond distances ranging from 2.29–2.86 Å. In the second Bi3+ site, Bi3+ is bonded in a 8-coordinate geometry to eightmore » O2- atoms. There are a spread of Bi–O bond distances ranging from 2.34–2.83 Å. There are six inequivalent O2- sites. In the first O2- site, O2- is bonded in a single-bond geometry to one Ti4+, three equivalent Pb2+, and one Bi3+ atom. In the second O2- site, O2- is bonded in a distorted bent 150 degrees geometry to two equivalent Ti4+ and two equivalent Pb2+ atoms. In the third O2- site, O2- is bonded in a 4-coordinate geometry to one Ti4+, one Fe3+, one Pb2+, and one Bi3+ atom. In the fourth O2- site, O2- is bonded in a distorted single-bond geometry to one Fe3+, one Pb2+, and three Bi3+ atoms. In the fifth O2- site, O2- is bonded to two Fe3+ and two Bi3+ atoms to form a mixture of distorted corner and edge-sharing OFe2Bi2 tetrahedra. In the sixth O2- site, O2- is bonded in a distorted single-bond geometry to one Fe3+ and four Bi3+ atoms.« less
