In the fifteenth O site, O(15) is bonded to one Li(1), one V(1), one V(3), and one Fe(2) atom to form distorted OLiV2Fe trigonal pyramids that share  a cornercorner with one O(11)LiVCrFe tetrahedra,  a cornercorner with one O(12)LiVCrFe tetrahedra, corners with two equivalent O(5)LiV2Cr tetrahedra,  an edgeedge with one O(11)LiVCrFe tetrahedra, and  an edgeedge with one O(12)LiVCrFe tetrahedra. In the sixteenth O site, O(16) is bonded in a rectangular see-saw-like geometry to one Li(2), one V(2), one Cr(2), and one Fe(2) atom. is represented by the Crystallographic Information File (CIF) [CIF]
