MgTi(SiO3)2 is Esseneite structured and crystallizes in the monoclinic C2/c space group. Mg(1) is bonded in a rectangular see-saw-like geometry to two equivalent O(2) and two equivalent O(3) atoms. Ti(1) is bonded to two equivalent O(2) and four equivalent O(3) atoms to form TiO6 octahedra that share corners with six equivalent Si(1)O4 tetrahedra and edges with two equivalent Ti(1)O6 octahedra. Si(1) is bonded to one O(2), one O(3), and two equivalent O(1) atoms to form SiO4 tetrahedra that share corners with three equivalent Ti(1)O6 octahedra and corners with two equivalent Si(1)O4 tetrahedra. The corner-sharing octahedral tilt angles range from 39-61°. There are three inequivalent O sites. In the first O site, O(1) is bonded in a bent 150 degrees geometry to two equivalent Si(1) atoms. In the second O site, O(2) is bonded in a 3-coordinate geometry to one Mg(1), one Ti(1), and one Si(1) atom. In the third O site, O(3) is bonded in a rectangular see-saw-like geometry to one Mg(1), two equivalent Ti(1), and one Si(1) atom.
