Materials Data on TaBi4ClO8 by Materials Project
Bi4TaO8Cl crystallizes in the orthorhombic Pbcn space group. The structure is three-dimensional. Ta5+ is bonded to six O2- atoms to form corner-sharing TaO6 octahedra. The corner-sharing octahedral tilt angles are 27°. There are a spread of Ta–O bond distances ranging from 1.91–2.12 Å. There are two inequivalent Bi3+ sites. In the first Bi3+ site, Bi3+ is bonded in a 4-coordinate geometry to four O2- and four equivalent Cl1- atoms. There are three shorter (2.23 Å) and one longer (2.32 Å) Bi–O bond lengths. There are a spread of Bi–Cl bond distances ranging from 3.35–3.55 Å. In the second Bi3+ site, Bi3+ is bonded in a 7-coordinate geometry to seven O2- atoms. There are a spread of Bi–O bond distances ranging from 2.27–2.85 Å. There are four inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted trigonal non-coplanar geometry to one Ta5+ and two equivalent Bi3+ atoms. In the second O2- site, O2- is bonded to four Bi3+ atoms to form a mixture of distorted edge and corner-sharing OBi4 tetrahedra. In the third O2- site, O2- is bonded to four Bi3+ atoms to form a mixture of distorted edge and corner-sharing OBi4 tetrahedra. In the fourth O2- site, O2- is bonded in a distorted bent 150 degrees geometry to two equivalent Ta5+ and one Bi3+ atom. Cl1- is bonded in a 8-coordinate geometry to eight equivalent Bi3+ atoms.
