Materials Data on Bi2(SO4)3 by Materials Project

Abstract

Bi2(SO4)3 crystallizes in the trigonal R-3c space group. The structure is three-dimensional. Bi3+ is bonded to six O2- atoms to form BiO6 octahedra that share corners with six equivalent SO4 tetrahedra. There are three shorter (2.33 Å) and three longer (2.37 Å) Bi–O bond lengths. 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 22–41°. There is two shorter (1.48 Å) and two longer (1.49 Å) S–O bond length. There are two 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 distorted bent 150 degrees geometry to one Bi3+ and one S6+ atom.
