TiAg2SiO5 crystallizes in the tetragonal P4/nmm space group. Ti(1) is bonded to one O(2) and four equivalent O(1) atoms to form distorted TiO5 trigonal bipyramids that share corners with four equivalent Ag(1)O6 octahedra, corners with four equivalent Si(1)O4 tetrahedra, and edges with four equivalent Ag(1)O6 octahedra. The corner-sharing octahedral tilt angles are 59°. Ag(1) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form distorted AgO6 octahedra that share corners with two equivalent Ag(1)O6 octahedra, corners with four equivalent Si(1)O4 tetrahedra, corners with two equivalent Ti(1)O5 trigonal bipyramids, edges with four equivalent Ag(1)O6 octahedra, and edges with two equivalent Ti(1)O5 trigonal bipyramids. The corner-sharing octahedral tilt angles are 62°. Si(1) is bonded to four equivalent O(1) atoms to form SiO4 tetrahedra that share corners with eight equivalent Ag(1)O6 octahedra and corners with four equivalent Ti(1)O5 trigonal bipyramids. The corner-sharing octahedral tilt angles are 59°. There are two 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 distorted single-bond geometry to one Ti(1) and four equivalent Ag(1) atoms.
