Mg(SiO2)16 is Low Tridymite-derived structured and crystallizes in the monoclinic P2/m space group. The structure consists of one 7439-95-4 atom inside a SiO2 framework. In the SiO2 framework, there are four inequivalent Si sites. In the first Si site, Si(1) is bonded to one O(2), one O(3), one O(6), and one O(8) atom to form corner-sharing SiO4 tetrahedra. In the second Si site, Si(2) is bonded to one O(10), one O(3), one O(4), and one O(7) atom to form corner-sharing SiO4 tetrahedra. In the third Si site, Si(3) is bonded to one O(1), one O(4), one O(7), and one O(9) atom to form corner-sharing SiO4 tetrahedra. In the fourth Si site, Si(4) is bonded to one O(2), one O(5), one O(8), and one O(9) atom to form corner-sharing SiO4 tetrahedra. There are ten inequivalent O sites. In the first O site, O(9) is bonded in a bent 150 degrees geometry to one Si(3) and one Si(4) atom. In the second O site, O(10) is bonded in a bent 150 degrees geometry to two equivalent Si(2) atoms.
