LuBa2Cu3O6 crystallizes in the tetragonal P4/mmm space group. The structure is three-dimensional. Ba2+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are four shorter (2.78 Å) and four longer (2.99 Å) Ba–O bond lengths. Lu3+ is bonded in a body-centered cubic geometry to eight equivalent O2- atoms. All Lu–O bond lengths are 2.38 Å. There are two inequivalent Cu+1.67+ sites. In the first Cu+1.67+ site, Cu+1.67+ is bonded in a linear geometry to two equivalent O2- atoms. Both Cu–O bond lengths are 1.81 Å. In the second Cu+1.67+ site, Cu+1.67+ is bonded to five O2- atoms to form distorted corner-sharing CuO5 square pyramids. There are four shorter (1.93 Å) and one longer (2.66 Å) Cu–O bond lengths. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded in a 4-coordinate geometry to two equivalent Ba2+, two equivalent Lu3+, and two equivalent Cu+1.67+ atoms. In the second O2- site, O2- is bonded in a 6-coordinate geometry to four equivalent Ba2+ and two Cu+1.67+ atoms.
