In the fourteenth O site, O(14) is bonded in a rectangular see-saw-like geometry to one Li(2), one Cr(1), one Mn(2), and one Sn(1) atom. In the fifteenth O site, O(15) is bonded to one Li(1), one Cr(2), one Cr(3), and one Mn(2) atom to form a mixture of distorted corner and edge-sharing OLiMnCr2 tetrahedra. In the sixteenth O site, O(16) is bonded in a rectangular see-saw-like geometry to one Li(2), one Cr(1), one Mn(2), and one Sn(2) atom.
