The structure described by BaCu2(AgO2)2 crystallizes in the tetragonal P4/nbm space group. Ba(1) is bonded in a 8-coordinate geometry to eight equivalent O(1) atoms. Ag(1) is bonded in a linear geometry to two equivalent O(1) atoms. Cu(1) is bonded in a linear geometry to two equivalent O(1) atoms. O(1) is bonded in a 4-coordinate geometry to two equivalent Ba(1), one Ag(1), and one Cu(1) atom. is represented by the CIF file [CIF]
