Materials Data on La2Ti3(BiO6)2 by Materials Project
Abstract
Bi2La2Ti3O12 crystallizes in the orthorhombic Fmm2 space group. The structure is three-dimensional. La3+ is bonded in a 12-coordinate geometry to twelve O2- atoms. There are a spread of La–O bond distances ranging from 2.53–3.06 Å. There are two inequivalent Ti4+ sites. In the first Ti4+ site, Ti4+ is bonded to six O2- atoms to form corner-sharing TiO6 octahedra. The corner-sharing octahedral tilt angles are 9°. There are a spread of Ti–O bond distances ranging from 1.89–1.98 Å. In the second Ti4+ site, Ti4+ is bonded in a 6-coordinate geometry to six O2- atoms. There are a spread of Ti–O bond distances ranging from 1.79–2.33 Å. Bi3+ is bonded in a 4-coordinate geometry to eight O2- atoms. There are four shorter (2.31 Å) and four longer (2.89 Å) Bi–O bond lengths. There are five inequivalent O2- sites. In the first O2- site, O2- is bonded in a 1-coordinate geometry to four equivalent La3+ and two Ti4+ atoms. In the second O2- site, O2- is bonded to four equivalent Bi3+ atoms to form a mixture of edge and corner-sharing OBi4 tetrahedra. In the third O2- site, O2- is bonded in a single-bond geometry to one Ti4+ and four equivalent Bi3+ atoms. Inmore »
