description: LiEr6B3O14 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. Li1+ is bonded in a 7-coordinate geometry to seven O2- atoms. There are a spread of Li–O bond distances ranging from 2.01–2.54 Å. There are six inequivalent Er3+ sites. In the first Er3+ site, Er3+ is bonded to seven O2- atoms to form a mixture of distorted edge and corner-sharing ErO7 pentagonal bipyramids. There are a spread of Er–O bond distances ranging from 2.22–2.41 Å. In the second Er3+ site, Er3+ is bonded in a 6-coordinate geometry to six O2- atoms. There are a spread of Er–O bond distances ranging from 2.26–2.50 Å. In the third Er3+ site, Er3+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of Er–O bond distances ranging from 2.25–2.79 Å. In the fourth Er3+ site, Er3+ is bonded to seven O2- atoms to form a mixture of distorted edge and corner-sharing ErO7 pentagonal bipyramids. There are a spread of Er–O bond distances ranging from 2.25–2.40 Å. In the fifth Er3+ site, Er3+ is bonded to seven O2- atoms to form a mixture of distorted edge and corner-sharing ErO7 pentagonal bipyramids. There are a spread of Er–O bond distances ranging from 2.26–2.39 Å. In the sixth Er3+ site, Er3+ is bonded in a 7-coordinate geometry to seven O2- atoms. There are a spread of Er–O bond distances ranging from 2.20–2.50 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 are a spread of B–O bond distances ranging from 1.37–1.40 Å. 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 Er3+ and one B3+ atom. In the second O2- site, O2- is bonded in a 1-coordinate geometry to one Li1+, two Er3+, and one B3+ atom. In the third O2- site, O2- is bonded to four Er3+ atoms to form a mixture of edge and corner-sharing OEr4 tetrahedra. In the fourth O2- site, O2- is bonded in a 4-coordinate geometry to one Li1+, two Er3+, and one B3+ atom. In the fifth O2- site, O2- is bonded in a distorted single-bond geometry to one Li1+, three Er3+, and one B3+ atom. In the sixth O2- site, O2- is bonded in a 1-coordinate geometry to one Li1+, two Er3+, and one B3+ atom. In the seventh O2- site, O2- is bonded in a 4-coordinate geometry to one Li1+, two Er3+, and one B3+ atom. In the eighth O2- site, O2- is bonded to four Er3+ atoms to form a mixture of distorted edge and corner-sharing OEr4 tetrahedra. In the ninth O2- site, O2- is bonded to four Er3+ atoms to form a mixture of edge and corner-sharing OEr4 tetrahedra. In the tenth O2- site, O2- is bonded to four Er3+ atoms to form a mixture of edge and corner-sharing OEr4 tetrahedra. In the eleventh O2- site, O2- is bonded to four Er3+ atoms to form a mixture of edge and corner-sharing OEr4 tetrahedra. In the twelfth O2- site, O2- is bonded in a distorted single-bond geometry to one Li1+, three Er3+, and one B3+ atom. In the thirteenth O2- site, O2- is bonded in a distorted single-bond geometry to one Li1+, two Er3+, and one B3+ atom. In the fourteenth O2- site, O2- is bonded in a distorted single-bond geometry to three Er3+ and one B3+ atom.
