Title: Materials Data on Sr3Co2Cu2S2O5 by Materials Project

Abstract

Sr3Co2Cu2S2O5 crystallizes in the tetragonal I4/mmm space group. The structure is three-dimensional. there are two inequivalent Sr2+ sites. In the first Sr2+ site, Sr2+ is bonded to twelve O2- atoms to form SrO12 cuboctahedra that share corners with four equivalent SrO12 cuboctahedra, faces with four equivalent SrO12 cuboctahedra, and faces with eight equivalent CoO5 square pyramids. There are four shorter (2.78 Å) and eight longer (2.96 Å) Sr–O bond lengths. In the second Sr2+ site, Sr2+ is bonded in a 4-coordinate geometry to four equivalent S2- and four equivalent O2- atoms. All Sr–S bond lengths are 3.26 Å. All Sr–O bond lengths are 2.48 Å. Co2+ is bonded to five O2- atoms to form CoO5 square pyramids that share corners with five equivalent CoO5 square pyramids and faces with four equivalent SrO12 cuboctahedra. There is one shorter (1.92 Å) and four longer (1.99 Å) Co–O bond length. Cu2+ is bonded to four equivalent S2- atoms to form a mixture of corner and edge-sharing CuS4 tetrahedra. All Cu–S bond lengths are 2.40 Å. S2- is bonded in a 8-coordinate geometry to four equivalent Sr2+ and four equivalent Cu2+ atoms. There are two inequivalent O2- sites. In the first O2- site, O2-more » is bonded in a 6-coordinate geometry to four Sr2+ and two equivalent Co2+ atoms. In the second O2- site, O2- is bonded to four equivalent Sr2+ and two equivalent Co2+ atoms to form a mixture of distorted corner and edge-sharing OSr4Co2 octahedra. The corner-sharing octahedral tilt angles are 0°.« less
