Materials Data on Sr4S3O by Materials Project

Abstract

Sr4S3O is Caswellsilverite-like structured and crystallizes in the cubic Pm-3m space group. The structure is three-dimensional. there are four inequivalent Sr2+ sites. In the first Sr2+ site, Sr2+ is bonded to four equivalent S2- and two equivalent O2- atoms to form SrS4O2 octahedra that share corners with six equivalent SrS4O2 octahedra and edges with twelve SrS6 octahedra. The corner-sharing octahedral tilt angles are 0°. All Sr–S bond lengths are 2.95 Å. Both Sr–O bond lengths are 2.95 Å. In the second Sr2+ site, Sr2+ is bonded to six equivalent S2- atoms to form SrS6 octahedra that share corners with six equivalent SrS6 octahedra and edges with twelve SrS4O2 octahedra. The corner-sharing octahedral tilt angles are 0°. All Sr–S bond lengths are 2.95 Å. In the third Sr2+ site, Sr2+ is bonded to four equivalent S2- and two equivalent O2- atoms to form a mixture of edge and corner-sharing SrS4O2 octahedra. The corner-sharing octahedral tilt angles are 0°. All Sr–S bond lengths are 2.95 Å. Both Sr–O bond lengths are 2.95 Å. In the fourth Sr2+ site, Sr2+ is bonded to four equivalent S2- and two equivalent O2- atoms to form a mixture of edge and corner-sharing SrS4O2 octahedra. The corner-sharing octahedral tilt angles are 0°. All Sr–S bond lengths are 2.95 Å. Both Sr–O bond lengths are 2.95 Å. S2- is bonded to six Sr2+ atoms to form SSr6 octahedra that share corners with six equivalent SSr6 octahedra, edges with four equivalent OSr6 octahedra, and edges with eight equivalent SSr6 octahedra. The corner-sharing octahedral tilt angles are 0°. O2- is bonded to six Sr2+ atoms to form OSr6 octahedra that share corners with six equivalent OSr6 octahedra and edges with twelve equivalent SSr6 octahedra. The corner-sharing octahedral tilt angles are 0°.
