Materials Data on GePd2 by Materials Project

Abstract

Pd2Ge crystallizes in the hexagonal P-62m 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 five Ge atoms. There are one shorter (2.66 Å) and four longer (2.73 Å) Pd–Ge bond lengths. In the second Pd site, Pd is bonded to four Ge atoms to form a mixture of distorted edge and corner-sharing PdGe4 tetrahedra. There are two shorter (2.51 Å) and two longer (2.53 Å) Pd–Ge bond lengths. There are two inequivalent Ge sites. In the first Ge site, Ge is bonded in a 9-coordinate geometry to nine Pd atoms. In the second Ge site, Ge is bonded in a 9-coordinate geometry to nine Pd atoms.
