In the second B site, B(2) is bonded in a trigonal planar geometry to one O(2), one O(3), and one O(5) atom. There are six inequivalent O sites. In the first O site, O(1) is bonded to one Li(1), two equivalent Mn(1), and one B(1) atom to form distorted edge-sharing OLiMn2B tetrahedra. In the second O site, O(2) is bonded to one Li(2), two equivalent Fe(1), and one B(2) atom to form distorted edge-sharing OLiFe2B tetrahedra. In the third O site, O(3) is bonded in a distorted rectangular see-saw-like geometry to one Li(1), one Li(2), one Fe(1), and one B(2) atom.
