LiAgO2 crystallizes in the monoclinic P2/m space group. Li(1) is bonded to two equivalent O(1) and two equivalent O(2) atoms to form LiO4 tetrahedra that share corners with two equivalent Li(1)O4 tetrahedra, corners with two equivalent O(1)Li2AgO tetrahedra, and  an edgeedge with one Li(1)O4 tetrahedra. There are two inequivalent Ag sites. In the first Ag site, Ag(1) is bonded in a square co-planar geometry to four equivalent O(2) atoms. In the second Ag site, Ag(2) is bonded in a linear geometry to two equivalent O(1) atoms. There are two inequivalent O sites. In the first O site, O(1) is bonded to two equivalent Li(1), one Ag(2), and one O(1) atom to form distorted OLi2AgO tetrahedra that share corners with two equivalent Li(1)O4 tetrahedra, corners with three equivalent O(1)Li2AgO tetrahedra, and corners with four equivalent O(2)Li2Ag2 tetrahedra. In the second O site, O(2) is bonded to two equivalent Li(1) and two equivalent Ag(1) atoms to form OLi2Ag2 tetrahedra that share corners with four equivalent O(2)Li2Ag2 tetrahedra, corners with four equivalent O(1)Li2AgO tetrahedra, and edges with two equivalent O(2)Li2Ag2 tetrahedra.

Both Li(1)-O(1) bond lengths are 1.96 Å. There is one shorter (1.94 Å) and one longer (1.97 Å) Li(1)-O(2) bond length. There are two inequivalent Ag sites. In the first Ag site, Ag(1) is bonded in a square co-planar geometry to four equivalent O(2) atoms. All Ag(1)-O(2) bond lengths are 2.04 Å. In the second Ag site, Ag(2) is bonded in a linear geometry to two equivalent O(1) atoms. Both Ag(2)-O(1) bond lengths are 2.19 Å. There are two inequivalent O sites. In the first O site, O(1) is bonded to two equivalent Li(1), one Ag(2), and one O(1) atom to form distorted OLi2AgO tetrahedra that share corners with two equivalent Li(1)O4 tetrahedra, corners with three equivalent O(1)Li2AgO tetrahedra, and corners with four equivalent O(2)Li2Ag2 tetrahedra. The O(1)-O(1) bond length is 1.48 Å. In the second O site, O(2) is bonded to two equivalent Li(1) and two equivalent Ag(1) atoms to form OLi2Ag2 tetrahedra that share corners with four equivalent O(2)Li2Ag2 tetrahedra, corners with four equivalent O(1)Li2AgO tetrahedra, and edges with two equivalent O(2)Li2Ag2 tetrahedra.
