The compound described by Sr3Cr2Cu2S2O5 crystallizes in the tetragonal I4/mmm space group. There are two inequivalent Sr sites. In the first Sr site, Sr(1) is bonded to four equivalent O(1) and eight equivalent O(2) atoms to form SrO12 cuboctahedra that share corners with four equivalent Sr(1)O12 cuboctahedra, faces with four equivalent Sr(1)O12 cuboctahedra, and faces with eight equivalent Cr(1)O5 square pyramids. In the second Sr site, Sr(2) is bonded in a 4-coordinate geometry to four equivalent S(1) and four equivalent O(2) atoms. Cr(1) is bonded to one O(1) and four equivalent O(2) atoms to form CrO5 square pyramids that share corners with five equivalent Cr(1)O5 square pyramids and faces with four equivalent Sr(1)O12 cuboctahedra. Cu(1) is bonded to four equivalent S(1) atoms to form a mixture of edge and corner-sharing CuS4 tetrahedra. S(1) is bonded in a 8-coordinate geometry to four equivalent Sr(2) and four equivalent Cu(1) atoms. There are two inequivalent O sites. In the first O site, O(1) is bonded in a distorted linear geometry to four equivalent Sr(1) and two equivalent Cr(1) atoms. In the second O site, O(2) is bonded in a 6-coordinate geometry to two equivalent Sr(1), two equivalent Sr(2), and two equivalent Cr(1) atoms. is represented by the CIF card [CIF]
