Materials Data on SrCuSO by Materials Project
SrCuSO crystallizes in the tetragonal I4/mmm space group. The structure is three-dimensional. Sr2+ is bonded in a 8-coordinate geometry to four equivalent S2- and four equivalent O2- atoms. All Sr–S bond lengths are 3.27 Å. All Sr–O bond lengths are 2.45 Å. Cu2+ is bonded to four equivalent S2- atoms to form a mixture of edge and corner-sharing CuS4 tetrahedra. All Cu–S bond lengths are 2.35 Å. S2- is bonded in a 8-coordinate geometry to four equivalent Sr2+ and four equivalent Cu2+ atoms. O2- is bonded in a distorted square co-planar geometry to four equivalent Sr2+ atoms.
