Materials Data on Lu2SiO5 by Materials Project
Abstract
Lu2SiO5 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 2.17–2.74 Å. In the second Lu3+ site, Lu3+ is bonded to seven O2- atoms to form LuO7 pentagonal bipyramids that share corners with four equivalent SiO4 tetrahedra, edges with three equivalent LuO7 pentagonal bipyramids, and an edgeedge with one SiO4 tetrahedra. There are a spread of Lu–O bond distances ranging from 2.20–2.38 Å. Si4+ is bonded to four O2- atoms to form SiO4 tetrahedra that share corners with four equivalent LuO7 pentagonal bipyramids and an edgeedge with one LuO7 pentagonal bipyramid. There are a spread of Si–O bond distances ranging from 1.63–1.68 Å. There are five inequivalent O2- sites. In the first O2- site, O2- is bonded to four Lu3+ atoms to form a mixture of edge and corner-sharing OLu4 tetrahedra. In the second O2- site, O2- is bonded in a 3-coordinate geometry to two equivalent Lu3+ and one Si4+ atom. In the third O2- site, O2- is bonded in a 1-coordinate geometry to three equivalentmore »
