Materials Data on Tb3Si2Cl5O6 by Materials Project
Abstract
Tb3Si2O6Cl5 crystallizes in the monoclinic C2/m space group. The structure is three-dimensional. there are two inequivalent Tb3+ sites. In the first Tb3+ site, Tb3+ is bonded to two O2- and five Cl1- atoms to form distorted TbCl5O2 pentagonal bipyramids that share corners with four equivalent TbCl5O2 pentagonal bipyramids, corners with two equivalent SiO4 tetrahedra, an edgeedge with one TbCl2O6 hexagonal bipyramid, and edges with two equivalent TbCl5O2 pentagonal bipyramids. Both Tb–O bond lengths are 2.24 Å. There are a spread of Tb–Cl bond distances ranging from 2.67–2.88 Å. In the second Tb3+ site, Tb3+ is bonded to six O2- and two equivalent Cl1- atoms to form distorted TbCl2O6 hexagonal bipyramids that share corners with four equivalent TbCl2O6 hexagonal bipyramids, edges with two equivalent TbCl5O2 pentagonal bipyramids, and edges with four equivalent SiO4 tetrahedra. There are four shorter (2.37 Å) and two longer (2.89 Å) Tb–O bond lengths. Both Tb–Cl bond lengths are 2.71 Å. Si4+ is bonded to four O2- atoms to form SiO4 tetrahedra that share corners with two equivalent TbCl5O2 pentagonal bipyramids, corners with two equivalent SiO4 tetrahedra, and edges with two equivalent TbCl2O6 hexagonal bipyramids. There is three shorter (1.63 Å) and one longer (1.65 Å) Si–Omore »
