Materials Data on NaTb(SiO3)2 by Materials Project
Abstract
NaTb(SiO3)2 crystallizes in the triclinic P-1 space group. The structure is two-dimensional and consists of one NaTb(SiO3)2 sheet oriented in the (1, 1, -1) direction. there are two inequivalent Na1+ sites. In the first Na1+ site, Na1+ is bonded in a 4-coordinate geometry to two equivalent Si4+ and two equivalent O2- atoms. Both Na–Si bond lengths are 2.16 Å. Both Na–O bond lengths are 1.87 Å. In the second Na1+ site, Na1+ is bonded in a single-bond geometry to one O2- atom. The Na–O bond length is 1.51 Å. There are two inequivalent Tb3+ sites. In the first Tb3+ site, Tb3+ is bonded in a distorted linear geometry to two equivalent O2- atoms. Both Tb–O bond lengths are 2.24 Å. In the second Tb3+ site, Tb3+ is bonded in a 1-coordinate geometry to three O2- atoms. There are a spread of Tb–O bond distances ranging from 1.82–2.23 Å. There are three inequivalent Si4+ sites. In the first Si4+ site, Si4+ is bonded in a distorted single-bond geometry to three O2- atoms. There are a spread of Si–O bond distances ranging from 0.99–1.86 Å. In the second Si4+ site, Si4+ is bonded in a 3-coordinate geometry to three O2- atoms. Theremore »
