Title: Materials Data on YCo4Ge by Materials Project

Abstract

YCo4Ge crystallizes in the orthorhombic Cmmm space group. The structure is three-dimensional. Y is bonded in a 6-coordinate geometry to fourteen Co and four equivalent Ge atoms. There are a spread of Y–Co bond distances ranging from 2.84–3.17 Å. All Y–Ge bond lengths are 3.19 Å. There are two inequivalent Co sites. In the first Co site, Co is bonded in a 12-coordinate geometry to three equivalent Y, four equivalent Co, and two equivalent Ge atoms. All Co–Co bond lengths are 2.46 Å. Both Co–Ge bond lengths are 2.46 Å. In the second Co site, Co is bonded to four equivalent Y, six Co, and two equivalent Ge atoms to form distorted CoY4Co6Ge2 cuboctahedra that share corners with four equivalent GeY4Co8 cuboctahedra, corners with twelve equivalent CoY4Co6Ge2 cuboctahedra, edges with four equivalent GeY4Co8 cuboctahedra, edges with six equivalent CoY4Co6Ge2 cuboctahedra, faces with four equivalent GeY4Co8 cuboctahedra, and faces with six equivalent CoY4Co6Ge2 cuboctahedra. Both Co–Co bond lengths are 2.48 Å. Both Co–Ge bond lengths are 2.47 Å. Ge is bonded to four equivalent Y and eight Co atoms to form distorted GeY4Co8 cuboctahedra that share corners with eight equivalent CoY4Co6Ge2 cuboctahedra, corners with eight equivalent GeY4Co8 cuboctahedra, edges with twomore » equivalent GeY4Co8 cuboctahedra, edges with eight equivalent CoY4Co6Ge2 cuboctahedra, faces with two equivalent GeY4Co8 cuboctahedra, and faces with eight equivalent CoY4Co6Ge2 cuboctahedra.« less
