Materials Data on Ce2Ga12Pd by Materials Project

Abstract

Ce2PdGa12 crystallizes in the tetragonal P4/nbm space group. The structure is three-dimensional. Ce is bonded in a 6-coordinate geometry to fourteen Ga atoms. There are a spread of Ce–Ga bond distances ranging from 3.21–3.41 Å. Pd is bonded in a body-centered cubic geometry to eight equivalent Ga atoms. All Pd–Ga bond lengths are 2.58 Å. There are four inequivalent Ga sites. In the first Ga site, Ga is bonded in a 9-coordinate geometry to four equivalent Ce and five Ga atoms. There are one shorter (2.44 Å) and four longer (2.64 Å) Ga–Ga bond lengths. In the second Ga site, Ga is bonded in a 2-coordinate geometry to two equivalent Ce, two equivalent Pd, and two equivalent Ga atoms. Both Ga–Ga bond lengths are 2.64 Å. In the third Ga site, Ga is bonded in a 4-coordinate geometry to one Ce and three Ga atoms. The Ga–Ga bond length is 2.59 Å. In the fourth Ga site, Ga is bonded in a 9-coordinate geometry to four equivalent Ce and five Ga atoms.
