Ba2CoAg2(SeO)2 crystallizes in the tetragonal I4/mmm space group. Ba(1) is bonded in a 8-coordinate geometry to four equivalent Se(1) and four equivalent O(1) atoms. Co(1) is bonded in a square co-planar geometry to four equivalent O(1) atoms. Ag(1) is bonded in a 4-coordinate geometry to four equivalent Se(1) atoms. Se(1) is bonded in a 8-coordinate geometry to four equivalent Ba(1) and four equivalent Ag(1) atoms. O(1) is bonded to four equivalent Ba(1) and two equivalent Co(1) atoms to form a mixture of edge, face, and corner-sharing OBa4Co2 octahedra. The corner-sharing octahedra are not tilted.
