In the third Li site, Li(3) is bonded to one O(3), one O(4), and two equivalent O(2) atoms to form distorted LiO4 tetrahedra that share corners with two equivalent Li(1)O4 tetrahedra, corners with two equivalent Li(2)O4 tetrahedra, corners with two equivalent Cr(1)O4 tetrahedra,  an edgeedge with one Li(1)O4 tetrahedra,  an edgeedge with one Li(2)O4 tetrahedra,  an edgeedge with one Li(3)O4 tetrahedra, and  an edgeedge with one Cr(1)O4 tetrahedra. Cr(1) is bonded to one O(1), one O(2), one O(3), and one O(4) atom to form CrO4 tetrahedra that share corners with two equivalent Li(1)O4 tetrahedra, corners with two equivalent Li(2)O4 tetrahedra, corners with two equivalent Li(3)O4 tetrahedra,  an edgeedge with one Li(1)O4 tetrahedra,  an edgeedge with one Li(2)O4 tetrahedra, and  an edgeedge with one Li(3)O4 tetrahedra. There are four inequivalent O sites. In the first O site, O(1) is bonded in a 3-coordinate geometry to two equivalent K(1), three equivalent K(2), one Li(1), one Li(2), and one Cr(1) atom. In the second O site, O(2) is bonded in a 5-coordinate geometry to one K(1), one K(2), one Li(1), one Li(2), two equivalent Li(3), and one Cr(1) atom. In the third O site, O(3) is bonded in a 4-coordinate geometry to one K(2), two equivalent K(1), one Li(1), one Li(2), one Li(3), and one Cr(1) atom. In the fourth O site, O(4) is bonded in a 4-coordinate geometry to one K(2), two equivalent K(1), one Li(1), one Li(2), one Li(3), and one Cr(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
