Ag2OTiO2 crystallizes in the monoclinic C2/c space group. Ti(1) is bonded to one O(2), one O(3), two equivalent O(1), and two equivalent O(4) atoms to form a mixture of distorted corner and edge-sharing TiO6 octahedra. The corner-sharing octahedral tilt angles are 23°. There are two inequivalent Ag sites. In the first Ag site, Ag(1) is bonded in a linear geometry to one O(1) and one O(2) atom. In the second Ag site, Ag(2) is bonded in a trigonal planar geometry to one O(3) and two equivalent O(2) atoms. There are four inequivalent O sites. In the first O site, O(4) is bonded to four equivalent Ti(1) atoms to form distorted OTi4 trigonal pyramids that share corners with two equivalent O(3)Ti2Ag2 tetrahedra,  an edgeedge with one O(3)Ti2Ag2 tetrahedra, and edges with two equivalent O(4)Ti4 trigonal pyramids. In the second O site, O(1) is bonded in a distorted trigonal planar geometry to two equivalent Ti(1) and one Ag(1) atom. In the third O site, O(2) is bonded in a 4-coordinate geometry to one Ti(1), one Ag(1), and two equivalent Ag(2) atoms. In the fourth O site, O(3) is bonded to two equivalent Ti(1) and two equivalent Ag(2) atoms to form a mixture of distorted corner and edge-sharing OTi2Ag2 tetrahedra.
