LiFeSiO4 crystallizes in the monoclinic Pc space group. Li(1) is bonded in a trigonal planar geometry to one O(2), one O(3), and one O(4) atom. Fe(1) is bonded to one O(1), one O(2), one O(3), and one O(4) atom to form FeO4 tetrahedra that share corners with four equivalent Si(1)O4 tetrahedra. Si(1) is bonded to one O(1), one O(2), one O(3), and one O(4) atom to form SiO4 tetrahedra that share corners with four equivalent Fe(1)O4 tetrahedra. There are four inequivalent O sites. In the first O site, O(1) is bonded in a bent 150 degrees geometry to one Fe(1) and one Si(1) atom. In the second O site, O(2) is bonded in a trigonal non-coplanar geometry to one Li(1), one Fe(1), and one Si(1) atom. In the third O site, O(3) is bonded in a trigonal planar geometry to one Li(1), one Fe(1), and one Si(1) atom. In the fourth O site, O(4) is bonded in a trigonal non-coplanar geometry to one Li(1), one Fe(1), and one Si(1) atom.
