Materials Data on Cd3S3O20 by Materials Project
(CdSO4)3(O2)4 crystallizes in the triclinic P1 space group. The structure is three-dimensional and consists of eight hydrogen peroxide molecules and one CdSO4 framework. In the CdSO4 framework, there are six inequivalent Cd sites. In the first Cd site, Cd is bonded to four O atoms to form distorted CdO4 tetrahedra that share corners with four SO4 tetrahedra. There are two shorter (2.17 Å) and two longer (2.21 Å) Cd–O bond lengths. In the second Cd site, Cd is bonded to four O atoms to form distorted CdO4 trigonal pyramids that share corners with four SO4 tetrahedra. There are a spread of Cd–O bond distances ranging from 2.17–2.22 Å. In the third Cd site, Cd is bonded to four O atoms to form distorted CdO4 tetrahedra that share corners with four SO4 tetrahedra. There are a spread of Cd–O bond distances ranging from 2.19–2.21 Å. In the fourth Cd site, Cd is bonded to four O atoms to form distorted CdO4 tetrahedra that share corners with four SO4 tetrahedra.
