Materials Data on Sr2CrCuSO3 by Materials Project
Abstract
Sr2CuCrO3S crystallizes in the tetragonal P4/nmm space group. The structure is three-dimensional. there are two inequivalent Sr2+ sites. In the first Sr2+ site, Sr2+ is bonded in a 8-coordinate geometry to four equivalent S2- and four equivalent O2- atoms. All Sr–S bond lengths are 3.15 Å. All Sr–O bond lengths are 2.55 Å. In the second Sr2+ site, Sr2+ is bonded in a 9-coordinate geometry to nine O2- atoms. There are a spread of Sr–O bond distances ranging from 2.45–2.81 Å. Cr3+ is bonded to five O2- atoms to form corner-sharing CrO5 square pyramids. There is one shorter (1.92 Å) and four longer (2.00 Å) Cr–O bond length. Cu1+ is bonded to four equivalent S2- atoms to form a mixture of edge and corner-sharing CuS4 tetrahedra. All Cu–S bond lengths are 2.42 Å. S2- is bonded in a 4-coordinate geometry to four equivalent Sr2+ and four equivalent Cu1+ atoms. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded to five equivalent Sr2+ and one Cr3+ atom to form distorted OSr5Cr octahedra that share corners with sixteen OSr5Cr octahedra, edges with eight equivalent OSr5Cr octahedra, and faces with four equivalent OSr4Cr2 octahedra.
