Abstract

Pd12PbBi3 is beta Cu3Ti-derived structured and crystallizes in the orthorhombic Pmm2 space group. The structure is three-dimensional. there are six inequivalent Pd sites. In the first Pd site, Pd is bonded to eight Pd, one Pb, and three Bi atoms to form PdBi3Pd8Pb cuboctahedra that share corners with four equivalent BiPd12 cuboctahedra, corners with fourteen PdBi3Pd8Pb cuboctahedra, edges with two equivalent PbPd12 cuboctahedra, edges with four BiPd12 cuboctahedra, edges with twelve PdBi3Pd8Pb cuboctahedra, a faceface with one PbPd12 cuboctahedra, faces with three BiPd12 cuboctahedra, and faces with sixteen PdBi3Pd8Pb cuboctahedra. There are a spread of Pd–Pd bond distances ranging from 2.90–2.94 Å. The Pd–Pb bond length is 2.90 Å. There are one shorter (2.92 Å) and two longer (2.93 Å) Pd–Bi bond lengths. In the second Pd site, Pd is bonded to eight Pd, two equivalent Pb, and two equivalent Bi atoms to form PdBi2Pd8Pb2 cuboctahedra that share corners with twelve PdBi4Pd8 cuboctahedra, edges with two equivalent PbPd12 cuboctahedra, edges with six BiPd12 cuboctahedra, edges with sixteen PdBi3Pd8Pb cuboctahedra, faces with two equivalent PbPd12 cuboctahedra, faces with two equivalent BiPd12 cuboctahedra, and faces with fourteen PdBi3Pd8Pb cuboctahedra. There are a spread of Pd–Pd bond distances ranging from 2.87–3.00 Å. There are one shorter (2.89 Å) and one longer (2.95 Å) Pd–Pb bond lengths. Both Pd–Bi bond lengths are 2.94 Å. In the third Pd site, Pd is bonded to eight Pd and four Bi atoms to form PdBi4Pd8 cuboctahedra that share corners with twelve PdBi4Pd8 cuboctahedra, edges with two equivalent PbPd12 cuboctahedra, edges with six BiPd12 cuboctahedra, edges with sixteen PdBi3Pd8Pb cuboctahedra, faces with four BiPd12 cuboctahedra, and faces with fourteen PdBi3Pd8Pb cuboctahedra. There are a spread of Pd–Pd bond distances ranging from 2.86–2.99 Å. There are a spread of Pd–Bi bond distances ranging from 2.88–2.98 Å. In the fourth Pd site, Pd is bonded to eight Pd, two equivalent Pb, and two equivalent Bi atoms to form PdBi2Pd8Pb2 cuboctahedra that share corners with four PdBi2Pd8Pb2 cuboctahedra, corners with four equivalent PbPd12 cuboctahedra, corners with four equivalent BiPd12 cuboctahedra, edges with twenty-four PdBi3Pd8Pb cuboctahedra, faces with two equivalent PbPd12 cuboctahedra, faces with four equivalent BiPd12 cuboctahedra, and faces with twelve PdBi3Pd8Pb cuboctahedra. Both Pd–Pb bond lengths are 2.93 Å. Both Pd–Bi bond lengths are 2.97 Å. In the fifth Pd site, Pd is bonded to eight Pd and four Bi atoms to form PdBi4Pd8 cuboctahedra that share corners with four PdBi2Pd8Pb2 cuboctahedra, corners with four equivalent PbPd12 cuboctahedra, corners with four equivalent BiPd12 cuboctahedra, edges with twenty-four PdBi3Pd8Pb cuboctahedra, faces with six BiPd12 cuboctahedra, and faces with twelve PdBi3Pd8Pb cuboctahedra. There are two shorter (2.93 Å) and two longer (2.96 Å) Pd–Bi bond lengths. In the sixth Pd site, Pd is bonded to eight Pd, one Pb, and three Bi atoms to form PdBi3Pd8Pb cuboctahedra that share corners with eight equivalent BiPd12 cuboctahedra, corners with ten PdBi3Pd8Pb cuboctahedra, edges with eighteen PdBi3Pd8Pb cuboctahedra, faces with two equivalent PbPd12 cuboctahedra, faces with four BiPd12 cuboctahedra, and faces with fourteen PdBi3Pd8Pb cuboctahedra. The Pd–Pb bond length is 2.93 Å. There are two shorter (2.93 Å) and one longer (2.95 Å) Pd–Bi bond lengths. Pb is bonded to twelve Pd atoms to form PbPd12 cuboctahedra that share corners with two equivalent PbPd12 cuboctahedra, corners with two equivalent BiPd12 cuboctahedra, corners with eight PdBi2Pd8Pb2 cuboctahedra, edges with two equivalent PbPd12 cuboctahedra, edges with six BiPd12 cuboctahedra, edges with sixteen PdBi3Pd8Pb cuboctahedra, faces with four equivalent BiPd12 cuboctahedra, and faces with fourteen PdBi3Pd8Pb cuboctahedra.
