Materials Data on La(GaPd)2 by Materials Project

Abstract

LaPd2Ga2 crystallizes in the tetragonal P4/nmm space group. The structure is three-dimensional. La is bonded in a 12-coordinate geometry to eight Pd and eight Ga atoms. There are four shorter (3.37 Å) and four longer (3.38 Å) La–Pd bond lengths. There are four shorter (3.36 Å) and four longer (3.40 Å) La–Ga bond lengths. There are two inequivalent Pd sites. In the first Pd site, Pd is bonded in a 4-coordinate geometry to four equivalent La and four equivalent Ga atoms. All Pd–Ga bond lengths are 2.55 Å. In the second Pd site, Pd is bonded in a 9-coordinate geometry to four equivalent La and five Ga atoms. There are one shorter (2.52 Å) and four longer (2.57 Å) Pd–Ga bond lengths. There are two inequivalent Ga sites. In the first Ga site, Ga is bonded in a 4-coordinate geometry to four equivalent La and four equivalent Pd atoms. In the second Ga site, Ga is bonded in a 5-coordinate geometry to four equivalent La and five Pd atoms.
