Materials Data on SrGa3Pd by Materials Project

Abstract

SrPdGa3 crystallizes in the orthorhombic Cmcm space group. The structure is three-dimensional. Sr is bonded in a 6-coordinate geometry to five equivalent Pd and twelve Ga atoms. There are a spread of Sr–Pd bond distances ranging from 3.35–3.69 Å. There are a spread of Sr–Ga bond distances ranging from 3.21–3.49 Å. Pd is bonded in a 5-coordinate geometry to five equivalent Sr and five Ga atoms. There are one shorter (2.54 Å) and four longer (2.58 Å) Pd–Ga bond lengths. There are two inequivalent Ga sites. In the first Ga site, Ga is bonded in a 1-coordinate geometry to four equivalent Sr, one Pd, and four equivalent Ga atoms. All Ga–Ga bond lengths are 2.69 Å. In the second Ga site, Ga is bonded in a distorted L-shaped geometry to four equivalent Sr, two equivalent Pd, and two equivalent Ga atoms.
