Materials Data on AsPd3Pb2 by Materials Project
Pd3Pb2As crystallizes in the orthorhombic Cmc2_1 space group. The structure is three-dimensional. there are two inequivalent Pd sites. In the first Pd site, Pd is bonded in a 5-coordinate geometry to four Pd, four equivalent Pb, and two equivalent As atoms. There are a spread of Pd–Pd bond distances ranging from 2.92–3.16 Å. There are a spread of Pd–Pb bond distances ranging from 2.81–3.36 Å. There are one shorter (2.54 Å) and one longer (2.58 Å) Pd–As bond lengths. In the second Pd site, Pd is bonded in a 6-coordinate geometry to two equivalent Pd, four equivalent Pb, and two equivalent As atoms. There are two shorter (2.86 Å) and two longer (2.93 Å) Pd–Pb bond lengths. There are one shorter (2.50 Å) and one longer (2.64 Å) Pd–As bond lengths. Pb is bonded in a 5-coordinate geometry to six Pd atoms. As is bonded in a 6-coordinate geometry to six Pd atoms.
