There are a spread of Ho–O bond distances ranging from 2.26–2.80 Å. In the fourth Ho3+ site, Ho3+ is bonded to seven O2- atoms to form a mixture of distorted edge and corner-sharing HoO7 pentagonal bipyramids. There are a spread of Ho–O bond distances ranging from 2.26–2.42 Å. In the fifth Ho3+ site, Ho3+ is bonded to seven O2- atoms to form a mixture of distorted edge and corner-sharing HoO7 pentagonal bipyramids. There are a spread of Ho–O bond distances ranging from 2.27–2.41 Å. In the sixth 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 2.22–2.52 Å. There are three inequivalent B3+ sites. In the first B3+ site, B3+ is bonded in a trigonal planar geometry to three O2- atoms. There is two shorter (1.38 Å) and one longer (1.39 Å) B–O bond length. In the second B3+ site, B3+ is bonded in a trigonal planar geometry to three O2- atoms. There is two shorter (1.38 Å) and one longer (1.40 Å) B–O bond length. In the third B3+ site, B3+ is bonded in a trigonal planar geometry to three O2- atoms. There are a spread of B–O bond distances ranging from 1.38–1.40 Å. There are fourteen inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted single-bond geometry to three Ho3+ and one B3+ atom. In the second O2- site, O2- is bonded in a 1-coordinate geometry to one Li1+, two Ho3+, and one B3+ atom. In the third O2- site, O2- is bonded to four Ho3+ atoms to form a mixture of edge and corner-sharing OHo4 tetrahedra. In the fourth O2- site, O2- is bonded in a 4-coordinate geometry to one Li1+, two Ho3+, and one B3+ atom.
