Ba2Cu(SO)2 crystallizes in the tetragonal P4/mmm space group. Ba(1) is bonded in a 8-coordinate geometry to four equivalent S(1) and four equivalent O(1) atoms. Cu(1) is bonded in a square co-planar geometry to four equivalent O(1) atoms. S(1) is bonded in a 5-coordinate geometry to four equivalent Ba(1) and one S(1) atom. O(1) is bonded to four equivalent Ba(1) and two equivalent Cu(1) atoms to form a mixture of face, corner, and edge-sharing OBa4Cu2 octahedra. The corner-sharing octahedra are not tilted.
