Materials Data on MnGe3 by Materials Project

Abstract

MnGe3 is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. The structure is three-dimensional. Mn is bonded to twelve equivalent Ge atoms to form MnGe12 cuboctahedra that share corners with twelve equivalent MnGe12 cuboctahedra, edges with twenty-four equivalent GeMn4Ge8 cuboctahedra, faces with six equivalent MnGe12 cuboctahedra, and faces with twelve equivalent GeMn4Ge8 cuboctahedra. All Mn–Ge bond lengths are 2.82 Å. Ge is bonded to four equivalent Mn and eight equivalent Ge atoms to form distorted GeMn4Ge8 cuboctahedra that share corners with twelve equivalent GeMn4Ge8 cuboctahedra, edges with eight equivalent MnGe12 cuboctahedra, edges with sixteen equivalent GeMn4Ge8 cuboctahedra, faces with four equivalent MnGe12 cuboctahedra, and faces with fourteen equivalent GeMn4Ge8 cuboctahedra. All Ge–Ge bond lengths are 2.82 Å.
