In the fifteenth O site, O(15) is bonded to one Li(1), one Fe(2), one Co(2), and one Co(3) atom to form distorted OLiFeCo2 tetrahedra that share  a cornercorner with one O(11)LiTiFeCo tetrahedra, corners with two equivalent O(5)LiTiCo2 tetrahedra,  a cornercorner with one O(12)LiTiFeCo trigonal pyramid, corners with two equivalent O(10)LiFeCo2 trigonal pyramids,  an edgeedge with one O(11)LiTiFeCo tetrahedra, and  an edgeedge with one O(12)LiTiFeCo trigonal pyramid. In the sixteenth O site, O(16) is bonded in a rectangular see-saw-like geometry to one Li(2), one Ti(2), one Fe(2), and one Co(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
