Materials Data on UGaPd by Materials Project

Abstract

UPdGa crystallizes in the orthorhombic Amm2 space group. The structure is three-dimensional. there are two inequivalent U sites. In the first U site, U is bonded in a 5-coordinate geometry to five Pd and six Ga atoms. There are four shorter (2.95 Å) and one longer (2.98 Å) U–Pd bond lengths. There are two shorter (3.14 Å) and four longer (3.33 Å) U–Ga bond lengths. In the second U site, U is bonded in a 5-coordinate geometry to five Pd and six Ga atoms. There are four shorter (2.95 Å) and one longer (2.98 Å) U–Pd bond lengths. There are two shorter (3.13 Å) and four longer (3.34 Å) U–Ga bond lengths. There are two inequivalent Pd sites. In the first Pd site, Pd is bonded in a 9-coordinate geometry to six U and three Ga atoms. There are two shorter (2.71 Å) and one longer (2.72 Å) Pd–Ga bond lengths. In the second Pd site, Pd is bonded in a 9-coordinate geometry to three U and six Ga atoms. There are four shorter (2.67 Å) and two longer (2.68 Å) Pd–Ga bond lengths. There are two inequivalent Ga sites. In the first Ga site, Ga is bonded in a 12-coordinate geometry to six U, four Pd, and two equivalent Ga atoms. Both Ga–Ga bond lengths are 2.85 Å. In the second Ga site, Ga is bonded in a 12-coordinate geometry to six U, four Pd, and two Ga atoms. The Ga–Ga bond length is 2.85 Å.
