Materials Data on UPd3 by Materials Project
UPd3 is Uranium Silicide-like structured and crystallizes in the hexagonal P6_3/mmc space group. The structure is three-dimensional. there are two inequivalent U sites. In the first U site, U is bonded to twelve Pd atoms to form UPd12 cuboctahedra that share corners with six equivalent UPd12 cuboctahedra, edges with twelve equivalent PdU4Pd8 cuboctahedra, faces with six equivalent PdU4Pd8 cuboctahedra, and faces with eight UPd12 cuboctahedra. There are six shorter (2.92 Å) and six longer (2.98 Å) U–Pd bond lengths. In the second U site, U is bonded to twelve Pd atoms to form UPd12 cuboctahedra that share corners with twelve equivalent UPd12 cuboctahedra, edges with twelve equivalent PdU4Pd8 cuboctahedra, faces with six equivalent UPd12 cuboctahedra, and faces with six equivalent PdU4Pd8 cuboctahedra. There are six shorter (2.92 Å) and six longer (2.96 Å) U–Pd bond lengths. There are two inequivalent Pd sites. In the first Pd site, Pd is bonded to four U and eight Pd atoms to form distorted PdU4Pd8 cuboctahedra that share corners with twelve equivalent PdU4Pd8 cuboctahedra, edges with eight UPd12 cuboctahedra, edges with eight equivalent PdU4Pd8 cuboctahedra, faces with four UPd12 cuboctahedra, and faces with four equivalent PdU4Pd8 cuboctahedra. There are a spread of Pd–Pd bond distances ranging from 2.86–2.98 Å. In the second Pd site, Pd is bonded in a distorted square co-planar geometry to four U and four equivalent Pd atoms.
