Ce4Cu3(SO)4 crystallizes in the tetragonal I-42m space group. Ce(1) is bonded in a 4-coordinate geometry to four equivalent S(1), two equivalent O(1), and two equivalent O(2) atoms. There are two inequivalent Cu sites. In the first Cu site, Cu(1) is bonded to four equivalent S(1) atoms to form edge-sharing CuS4 tetrahedra. In the second Cu site, Cu(2) is bonded to four equivalent S(1) atoms to form a mixture of corner and edge-sharing CuS4 tetrahedra. S(1) is bonded in a 7-coordinate geometry to four equivalent Ce(1), one Cu(1), and two equivalent Cu(2) atoms. There are two inequivalent O sites. In the first O site, O(1) is bonded to four equivalent Ce(1) atoms to form a mixture of corner and edge-sharing OCe4 tetrahedra. In the second O site, O(2) is bonded to four equivalent Ce(1) atoms to form a mixture of corner and edge-sharing OCe4 tetrahedra.
Ce4Cu3(SO)4 crystallizes in the tetragonal I-42m space group. Ce(1) is bonded in a 4-coordinate geometry to four equivalent S(1), two equivalent O(1), and two equivalent O(2) atoms. There are two shorter (3.11 Å) and two longer (3.12 Å) Ce(1)-S(1) bond lengths. Both Ce(1)-O(1) bond lengths are 2.33 Å. Both Ce(1)-O(2) bond lengths are 2.33 Å. There are two inequivalent Cu sites. In the first Cu site, Cu(1) is bonded to four equivalent S(1) atoms to form edge-sharing CuS4 tetrahedra. All Cu(1)-S(1) bond lengths are 2.38 Å. In the second Cu site, Cu(2) is bonded to four equivalent S(1) atoms to form a mixture of corner and edge-sharing CuS4 tetrahedra. All Cu(2)-S(1) bond lengths are 2.38 Å.
