The material structure described by LuBa2Cu3O6 crystallizes in the tetragonal P4/mmm space group. Ba(1) is bonded in a 8-coordinate geometry to four equivalent O(1) and four equivalent O(2) atoms. Lu(1) is bonded in a body-centered cubic geometry to eight equivalent O(1) atoms. There are two inequivalent Cu sites. In the first Cu site, Cu(1) is bonded in a linear geometry to two equivalent O(2) atoms. In the second Cu site, Cu(2) is bonded in a distorted square co-planar geometry to one O(2) and four equivalent O(1) atoms. There are two inequivalent O sites. In the first O site, O(1) is bonded in a 6-coordinate geometry to two equivalent Ba(1), two equivalent Lu(1), and two equivalent Cu(2) atoms. In the second O site, O(2) is bonded in a 6-coordinate geometry to four equivalent Ba(1), one Cu(1), and one Cu(2) atom. is represented by the CIF file [CIF]
