Materials Data on Y3Si3Pd2 by Materials Project

Abstract

Y3Pd2Si3 crystallizes in the orthorhombic Cmcm space group. The structure is three-dimensional. there are two inequivalent Y sites. In the first Y site, Y is bonded in a 10-coordinate geometry to four equivalent Pd and six Si atoms. There are a spread of Y–Pd bond distances ranging from 3.06–3.16 Å. There are a spread of Y–Si bond distances ranging from 3.01–3.11 Å. In the second Y site, Y is bonded in a 9-coordinate geometry to four equivalent Pd and five Si atoms. All Y–Pd bond lengths are 3.15 Å. There are a spread of Y–Si bond distances ranging from 3.00–3.10 Å. Pd is bonded in a 10-coordinate geometry to six Y and four Si atoms. There are a spread of Pd–Si bond distances ranging from 2.50–2.74 Å. There are two inequivalent Si sites. In the first Si site, Si is bonded in a 9-coordinate geometry to seven Y and two equivalent Pd atoms. In the second Si site, Si is bonded in a 10-coordinate geometry to five Y, three equivalent Pd, and one Si atom. The Si–Si bond length is 2.48 Å.
