Materials Data on Dy2Si3 by Materials Project

Abstract

Dy2Si3 crystallizes in the orthorhombic Imm2 space group. The structure is three-dimensional. there are two inequivalent Dy sites. In the first Dy site, Dy is bonded in a 8-coordinate geometry to eight Si atoms. There are a spread of Dy–Si bond distances ranging from 2.92–3.09 Å. In the second Dy site, Dy is bonded in a 10-coordinate geometry to ten Si atoms. There are a spread of Dy–Si bond distances ranging from 2.97–3.12 Å. There are three inequivalent Si sites. In the first Si site, Si is bonded in a 7-coordinate geometry to six Dy and one Si atom. The Si–Si bond length is 2.33 Å. In the second Si site, Si is bonded in a 8-coordinate geometry to six Dy and two equivalent Si atoms. Both Si–Si bond lengths are 2.38 Å. In the third Si site, Si is bonded in a 9-coordinate geometry to six Dy and three Si atoms.
