Materials Data on Lu6TeO12 by Materials Project
Lu6TeO12 crystallizes in the trigonal R-3 space group. The structure is three-dimensional. Lu3+ is bonded in a 7-coordinate geometry to seven O2- atoms. There are a spread of Lu–O bond distances ranging from 2.15–2.74 Å. Te6+ is bonded in an octahedral geometry to six equivalent O2- atoms. All Te–O bond lengths are 1.97 Å. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded in a 4-coordinate geometry to three equivalent Lu3+ and one Te6+ atom. In the second O2- site, O2- is bonded to four equivalent Lu3+ atoms to form a mixture of corner and edge-sharing OLu4 tetrahedra.
