The material structure described by SrAgO2 crystallizes in the monoclinic C2/m space group. Sr(1) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form a mixture of corner and edge-sharing SrO6 octahedra. The corner-sharing octahedral tilt angles range from 14-36°. There are two inequivalent Ag sites. In the first Ag site, Ag(1) is bonded in a distorted square co-planar geometry to two equivalent O(1) and 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 Sr(1), one Ag(1), and one Ag(2) atom to form a mixture of distorted corner and edge-sharing OSr4Ag2 octahedra. The corner-sharing octahedra are not tilted. In the second O site, O(2) is bonded in a distorted see-saw-like geometry to two equivalent Sr(1), one Ag(1), and one Ag(2) atom. is represented by the Crystallographic Information File (CIF) [CIF]
