Materials Data on MnNiGe by Materials Project

Abstract

MnNiGe crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. Mn is bonded in a 5-coordinate geometry to six equivalent Ni and five equivalent Ge atoms. There are a spread of Mn–Ni bond distances ranging from 2.79–2.91 Å. There are a spread of Mn–Ge bond distances ranging from 2.54–2.63 Å. Ni is bonded in a 12-coordinate geometry to six equivalent Mn, two equivalent Ni, and four equivalent Ge atoms. Both Ni–Ni bond lengths are 2.64 Å. There are a spread of Ni–Ge bond distances ranging from 2.33–2.40 Å. Ge is bonded in a 9-coordinate geometry to five equivalent Mn and four equivalent Ni atoms.
