Materials Data on Sb(SO4)2 by Materials Project

Abstract

Sb(SO4)2 crystallizes in the orthorhombic Pbca space group. The structure is three-dimensional. Sb is bonded to six O atoms to form SbO6 octahedra that share corners with six SO4 tetrahedra. There are a spread of Sb–O bond distances ranging from 2.14–2.20 Å. There are two inequivalent S sites. In the first S site, S is bonded to four O atoms to form SO4 tetrahedra that share corners with three equivalent SbO6 octahedra. The corner-sharing octahedra tilt angles range from 43–50°. There are a spread of S–O bond distances ranging from 1.43–1.53 Å. In the second S site, S is bonded to four O atoms to form SO4 tetrahedra that share corners with three equivalent SbO6 octahedra. The corner-sharing octahedra tilt angles range from 48–50°. There are a spread of S–O bond distances ranging from 1.43–1.53 Å. There are eight inequivalent O sites. In the first O site, O is bonded in a distorted bent 120 degrees geometry to one Sb and one S atom. In the second O site, O is bonded in a distorted bent 120 degrees geometry to one Sb and one S atom. In the third O site, O is bonded in a distorted bent 150 degrees geometry to one Sb and one S atom. In the fourth O site, O is bonded in a single-bond geometry to one S atom. In the fifth O site, O is bonded in a distorted bent 120 degrees geometry to one Sb and one S atom. In the sixth O site, O is bonded in a single-bond geometry to one S atom. In the seventh O site, O is bonded in a distorted bent 120 degrees geometry to one Sb and one S atom. In the eighth O site, O is bonded in a distorted bent 150 degrees geometry to one Sb and one S atom.
