In the sixteenth O site, O(16) is bonded to one La(2), one La(4), one La(5), one La(6), one Cu(1), and one Cu(2) atom to form distorted OLa4Cu2 octahedra that share  a cornercorner with one O(1)La4Cu2 octahedra,  a cornercorner with one O(3)La4Cu square pyramid, corners with two equivalent O(5)La5 trigonal bipyramids, corners with three equivalent O(8)La5 trigonal bipyramids, edges with two equivalent O(9)La4Cu square pyramids,  a faceface with one O(11)La4Cu2 octahedra,  a faceface with one O(12)La4Cu2 octahedra,  a faceface with one O(10)La4Cu square pyramid, and  a faceface with one O(4)La4Cu square pyramid. The corner-sharing octahedra are not tilted. is represented by the CIF file [CIF]
