Materials Data on CdSO3 by Materials Project

Abstract

CdSO3 crystallizes in the trigonal R-3 space group. The structure is three-dimensional. Cd2+ is bonded to six O2- atoms to form a mixture of edge and corner-sharing CdO6 octahedra. The corner-sharing octahedral tilt angles are 74°. There are a spread of Cd–O bond distances ranging from 2.28–2.40 Å. S4+ is bonded in a trigonal non-coplanar geometry to three O2- atoms. There is two shorter (1.55 Å) and one longer (1.56 Å) S–O bond length. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted trigonal planar geometry to two equivalent Cd2+ and one S4+ atom. In the second O2- site, O2- is bonded in a 3-coordinate geometry to two equivalent Cd2+ and one S4+ atom. In the third O2- site, O2- is bonded in a distorted trigonal planar geometry to two equivalent Cd2+ and one S4+ atom.
