The structure described by MgTi2Si2(Ag2O5)2 crystallizes in the tetragonal P-4m2 space group. Mg(1) is bonded in a 4-coordinate geometry to four equivalent O(2) atoms. Ti(1) is bonded to one O(3), two equivalent O(1), and two equivalent O(2) atoms to form distorted TiO5 trigonal bipyramids that share corners with two equivalent Si(1)O4 tetrahedra and corners with two equivalent Si(2)O4 tetrahedra. Ag(1) is bonded in a 2-coordinate geometry to two equivalent O(1) atoms. There are two inequivalent Si sites. In the first Si site, Si(1) is bonded to four equivalent O(1) atoms to form SiO4 tetrahedra that share corners with four equivalent Ti(1)O5 trigonal bipyramids. In the second Si site, Si(2) is bonded to four equivalent O(2) atoms to form SiO4 tetrahedra that share corners with four equivalent Ti(1)O5 trigonal bipyramids. There are three inequivalent O sites. In the first O site, O(1) is bonded in a 4-coordinate geometry to one Ti(1), two equivalent Ag(1), and one Si(1) atom. In the second O site, O(2) is bonded in a 3-coordinate geometry to one Mg(1), one Ti(1), and one Si(2) atom. In the third O site, O(3) is bonded in a single-bond geometry to one Ti(1) atom. is represented by the CIF file [CIF]
