BaAgO2 crystallizes in the monoclinic C2/m space group. Ba(1) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form a mixture of distorted corner and edge-sharing BaO6 octahedra. The corner-sharing octahedral tilt angles range from 18-46°. There are two inequivalent Ag sites. In the first Ag site, Ag(1) is bonded in a linear geometry to two equivalent O(2) atoms. In the second Ag site, Ag(2) is bonded in a square co-planar geometry to two equivalent O(1) and two equivalent O(2) atoms. There are two inequivalent O sites. In the first O site, O(1) is bonded to four equivalent Ba(1) and one Ag(2) atom to form a mixture of distorted corner and edge-sharing OBa4Ag square pyramids. In the second O site, O(2) is bonded in a 4-coordinate geometry to two equivalent Ba(1), one Ag(1), and one Ag(2) atom.

The corner-sharing octahedral tilt angles range from 18-46°. Both Ba(1)-O(2) bond lengths are 2.72 Å. There are two shorter (2.75 Å) and two longer (2.79 Å) Ba(1)-O(1) bond lengths. There are two inequivalent Ag sites. In the first Ag site, Ag(1) is bonded in a linear geometry to two equivalent O(2) atoms. Both Ag(1)-O(2) bond lengths are 2.11 Å. In the second Ag site, Ag(2) is bonded in a square co-planar geometry to two equivalent O(1) and two equivalent O(2) atoms. Both Ag(2)-O(1) bond lengths are 2.07 Å. Both Ag(2)-O(2) bond lengths are 2.11 Å. There are two inequivalent O sites.
