Ba2Ho(CuO2)3 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. Ho(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 distorted square co-planar geometry to one O(2) and four equivalent O(1) atoms. In the second Cu site, Cu(2) is bonded in a linear geometry to two equivalent O(2) 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 Ho(1), and two equivalent Cu(1) 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.
