Title: Materials Data on Nd2Si2O7 by Materials Project

Abstract

Nd2Si2O7 crystallizes in the orthorhombic P2_12_12_1 space group. The structure is three-dimensional. there are two inequivalent Nd3+ sites. In the first Nd3+ site, Nd3+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of Nd–O bond distances ranging from 2.28–2.69 Å. In the second Nd3+ site, Nd3+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of Nd–O bond distances ranging from 2.36–2.77 Å. There are two inequivalent Si4+ sites. In the first Si4+ site, Si4+ is bonded to four O2- atoms to form corner-sharing SiO4 tetrahedra. There are a spread of Si–O bond distances ranging from 1.63–1.65 Å. In the second Si4+ site, Si4+ is bonded to four O2- atoms to form corner-sharing SiO4 tetrahedra. There are a spread of Si–O bond distances ranging from 1.62–1.66 Å. There are seven inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted single-bond geometry to three Nd3+ and one Si4+ atom. In the second O2- site, O2- is bonded in a 3-coordinate geometry to two Nd3+ and one Si4+ atom. In the third O2- site, O2- is bonded in a 1-coordinate geometry to three Nd3+ and onemore » Si4+ atom. In the fourth O2- site, O2- is bonded in a bent 120 degrees geometry to two Si4+ atoms. In the fifth O2- site, O2- is bonded in a 1-coordinate geometry to two Nd3+ and one Si4+ atom. In the sixth O2- site, O2- is bonded in a 1-coordinate geometry to three Nd3+ and one Si4+ atom. In the seventh O2- site, O2- is bonded in a 1-coordinate geometry to three Nd3+ and one Si4+ atom.« less
