Materials Data on Bi2(SO4)3 by Materials Project

Abstract

Bi2(SO4)3 crystallizes in the monoclinic C2/c space group. The structure is three-dimensional. Bi3+ is bonded to six O2- atoms to form BiO6 octahedra that share corners with six SO4 tetrahedra and an edgeedge with one BiO6 octahedra. There are a spread of Bi–O bond distances ranging from 2.26–2.54 Å. There are two inequivalent S6+ sites. In the first S6+ site, S6+ is bonded to four O2- atoms to form SO4 tetrahedra that share corners with four equivalent BiO6 octahedra. The corner-sharing octahedra tilt angles range from 32–55°. There are a spread of S–O bond distances ranging from 1.43–1.56 Å. In the second S6+ site, S6+ is bonded to four O2- atoms to form SO4 tetrahedra that share corners with four equivalent BiO6 octahedra. The corner-sharing octahedra tilt angles range from 16–33°. There is two shorter (1.48 Å) and two longer (1.49 Å) S–O bond length. There are six inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Bi3+ and one S6+ atom. In the second O2- site, O2- is bonded in a single-bond geometry to one S6+ atom. In the third O2- site, O2- is bonded in a 2-coordinate geometry to one Bi3+ and one S6+ atom. In the fourth O2- site, O2- is bonded in a 3-coordinate geometry to two equivalent Bi3+ and one S6+ atom. In the fifth O2- site, O2- is bonded in a distorted linear geometry to one Bi3+ and one S6+ atom. In the sixth O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Bi3+ and one S6+ atom.
