Materials Data on MnGe2Pd3 by Materials Project

Abstract

Pd2(MnPd)Ge2 crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. Mn is bonded in a 10-coordinate geometry to six Pd and four equivalent Ge atoms. There are a spread of Mn–Pd bond distances ranging from 2.78–2.85 Å. There are two shorter (2.69 Å) and two longer (2.74 Å) Mn–Ge bond lengths. There are three inequivalent Pd sites. In the first Pd site, Pd is bonded in a 6-coordinate geometry to two equivalent Mn and four Ge atoms. There are a spread of Pd–Ge bond distances ranging from 2.54–2.58 Å. In the second Pd site, Pd is bonded in a 8-coordinate geometry to four equivalent Mn and four Ge atoms. There are a spread of Pd–Ge bond distances ranging from 2.58–2.62 Å. In the third Pd site, Pd is bonded in a 5-coordinate geometry to five Ge atoms. There are a spread of Pd–Ge bond distances ranging from 2.50–2.70 Å. There are two inequivalent Ge sites. In the first Ge site, Ge is bonded in a 8-coordinate geometry to eight Pd atoms. In the second Ge site, Ge is bonded in a 9-coordinate geometry to four equivalent Mn and five Pd atoms.
