Materials Data on Te2Pd3Pb2 by Materials Project
Pd3Pb2Te2 crystallizes in the orthorhombic Pmmn space group. The structure is three-dimensional. there are two inequivalent Pd sites. In the first Pd site, Pd is bonded in a 6-coordinate geometry to four Pd, four Pb, and two equivalent Te atoms. There are two shorter (3.02 Å) and two longer (3.03 Å) Pd–Pd bond lengths. There are two shorter (2.96 Å) and two longer (3.15 Å) Pd–Pb bond lengths. Both Pd–Te bond lengths are 2.64 Å. In the second Pd site, Pd is bonded in a 10-coordinate geometry to four equivalent Pd, four Pb, and two equivalent Te atoms. There are a spread of Pd–Pb bond distances ranging from 3.03–3.45 Å. Both Pd–Te bond lengths are 2.66 Å. There are two inequivalent Pb sites. In the first Pb site, Pb is bonded in a 6-coordinate geometry to six Pd and four equivalent Te atoms. All Pb–Te bond lengths are 3.57 Å. In the second Pb site, Pb is bonded in a distorted hexagonal planar geometry to six Pd atoms. Te is bonded in a 6-coordinate geometry to three Pd and two equivalent Pb atoms.
