Ho2Te5O13 crystallizes in the triclinic P-1 space group. The structure is two-dimensional and consists of one Ho2Te5O13 sheet oriented in the (0, 0, 1) direction. there are two inequivalent Ho3+ sites. In the first Ho3+ site, Ho3+ is bonded in a 7-coordinate geometry to seven O2- atoms. There are a spread of Ho–O bond distances ranging from 2.21–2.81 Å. In the second Ho3+ site, Ho3+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of Ho–O bond distances ranging from 2.30–2.64 Å. There are five inequivalent Te4+ sites. In the first Te4+ site, Te4+ is bonded in a 4-coordinate geometry to four O2- atoms. There are a spread of Te–O bond distances ranging from 1.91–2.46 Å. In the second Te4+ site, Te4+ is bonded in a 4-coordinate geometry to four O2- atoms. There are a spread of Te–O bond distances ranging from 1.88–2.54 Å. In the third Te4+ site, Te4+ is bonded in a 3-coordinate geometry to three O2- atoms. There are a spread of Te–O bond distances ranging from 1.90–1.94 Å. In the fourth Te4+ site, Te4+ is bonded in a 5-coordinate geometry to four O2- atoms. There are a spread of Te–O bond distances ranging from 1.90–2.75 Å. In the fifth Te4+ site, Te4+ is bonded in a rectangular see-saw-like geometry to four O2- atoms. There are a spread of Te–O bond distances ranging from 1.89–2.15 Å. There are thirteen inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted trigonal planar geometry to two Ho3+ and one Te4+ atom. In the second O2- site, O2- is bonded in a distorted trigonal non-coplanar geometry to two Ho3+ and one Te4+ atom. In the third O2- site, O2- is bonded in a 3-coordinate geometry to one Ho3+ and two Te4+ atoms. In the fourth O2- site, O2- is bonded in a distorted bent 150 degrees geometry to two Te4+ atoms. In the fifth O2- site, O2- is bonded in a linear geometry to one Ho3+ and one Te4+ atom. In the sixth O2- site, O2- is bonded in a 3-coordinate geometry to one Ho3+ and two Te4+ atoms. In the seventh O2- site, O2- is bonded in a 2-coordinate geometry to one Ho3+ and two Te4+ atoms. In the eighth O2- site, O2- is bonded in a 2-coordinate geometry to two Ho3+ and one Te4+ atom. In the ninth O2- site, O2- is bonded in a bent 120 degrees geometry to two Te4+ atoms. In the tenth O2- site, O2- is bonded in a 2-coordinate geometry to one Ho3+ and one Te4+ atom. In the eleventh O2- site, O2- is bonded in a distorted bent 120 degrees geometry to two Te4+ atoms. In the twelfth O2- site, O2- is bonded in a 3-coordinate geometry to two Ho3+ and one Te4+ atom. In the thirteenth O2- site, O2- is bonded in a 2-coordinate geometry to two equivalent Ho3+ and one Te4+ atom.
