Materials Data on Lu2GeO5 by Materials Project
Lu2GeO5 is Baddeleyite-derived structured and crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. there are two inequivalent Lu3+ sites. In the first Lu3+ site, Lu3+ is bonded in a 7-coordinate geometry to seven O2- atoms. There are a spread of Lu–O bond distances ranging from 2.18–2.53 Å. In the second Lu3+ site, Lu3+ is bonded to seven O2- atoms to form distorted LuO7 pentagonal bipyramids that share corners with four equivalent GeO4 tetrahedra, edges with three equivalent LuO7 pentagonal bipyramids, and an edgeedge with one GeO4 tetrahedra. There are a spread of Lu–O bond distances ranging from 2.21–2.40 Å. Ge4+ is bonded to four O2- atoms to form GeO4 tetrahedra that share corners with four equivalent LuO7 pentagonal bipyramids and an edgeedge with one LuO7 pentagonal bipyramid. There are a spread of Ge–O bond distances ranging from 1.74–1.82 Å. There are five inequivalent O2- sites. In the first O2- site, O2- is bonded in a 4-coordinate geometry to three equivalent Lu3+ and one Ge4+ atom. In the second O2- site, O2- is bonded to four Lu3+ atoms to form a mixture of edge and corner-sharing OLu4 tetrahedra. In the third O2- site, O2- is bonded in a 4-coordinate geometry to three Lu3+ and one Ge4+ atom. In the fourth O2- site, O2- is bonded in a 3-coordinate geometry to two equivalent Lu3+ and one Ge4+ atom. In the fifth O2- site, O2- is bonded in a distorted trigonal non-coplanar geometry to two equivalent Lu3+ and one Ge4+ atom.
