Title: Materials Data on Mn2Co3Ge by Materials Project

Abstract

Mn2Co3Ge crystallizes in the hexagonal P6_3/mmc space group. The structure is three-dimensional. Mn is bonded in a 12-coordinate geometry to four equivalent Mn, nine equivalent Co, and three equivalent Ge atoms. There are one shorter (2.82 Å) and three longer (2.94 Å) Mn–Mn bond lengths. There are three shorter (2.74 Å) and six longer (2.78 Å) Mn–Co bond lengths. All Mn–Ge bond lengths are 2.81 Å. Co is bonded to six equivalent Mn, four equivalent Co, and two equivalent Ge atoms to form distorted CoMn6Co4Ge2 cuboctahedra that share corners with four equivalent GeMn6Co6 cuboctahedra, corners with fourteen equivalent CoMn6Co4Ge2 cuboctahedra, edges with six equivalent CoMn6Co4Ge2 cuboctahedra, faces with six equivalent GeMn6Co6 cuboctahedra, and faces with twelve equivalent CoMn6Co4Ge2 cuboctahedra. There are two shorter (2.30 Å) and two longer (2.50 Å) Co–Co bond lengths. Both Co–Ge bond lengths are 2.39 Å. Ge is bonded to six equivalent Mn and six equivalent Co atoms to form GeMn6Co6 cuboctahedra that share corners with twelve equivalent CoMn6Co4Ge2 cuboctahedra, edges with six equivalent GeMn6Co6 cuboctahedra, faces with two equivalent GeMn6Co6 cuboctahedra, and faces with eighteen equivalent CoMn6Co4Ge2 cuboctahedra.
