In the fifteenth O site, O(15) is bonded to one Li(1), one Cr(2), one Cr(3), and one Sb(2) atom to form distorted OLiCr2Sb trigonal pyramids that share  a cornercorner with one O(3)LiCrCu2 tetrahedra,  a cornercorner with one O(12)LiCrCuSb tetrahedra, corners with two equivalent O(5)LiCr2Cu tetrahedra,  an edgeedge with one O(12)LiCrCuSb tetrahedra, and  an edgeedge with one O(13)LiCr2Cu trigonal pyramid. In the sixteenth O site, O(16) is bonded in a rectangular see-saw-like geometry to one Li(2), one Cr(1), one Cu(2), and one Sb(2) atom.
