Materials Data on Ge3Au by Materials Project
Abstract
AuGe3 is Uranium Silicide-like structured and crystallizes in the tetragonal I4/mmm space group. The structure is three-dimensional. Au is bonded to twelve Ge atoms to form AuGe12 cuboctahedra that share corners with four equivalent AuGe12 cuboctahedra, edges with eight equivalent AuGe12 cuboctahedra, edges with sixteen equivalent GeGe8Au4 cuboctahedra, faces with four equivalent AuGe12 cuboctahedra, and faces with eight equivalent GeGe8Au4 cuboctahedra. There are four shorter (2.95 Å) and eight longer (3.07 Å) Au–Ge bond lengths. There are two inequivalent Ge sites. In the first Ge site, Ge is bonded to four equivalent Au and eight Ge atoms to form distorted GeGe8Au4 cuboctahedra that share corners with twelve equivalent GeGe8Au4 cuboctahedra, edges with eight equivalent AuGe12 cuboctahedra, edges with eight equivalent GeGe8Au4 cuboctahedra, faces with four equivalent AuGe12 cuboctahedra, and faces with ten equivalent GeGe8Au4 cuboctahedra. There are four shorter (2.95 Å) and four longer (3.07 Å) Ge–Ge bond lengths. In the second Ge site, Ge is bonded in a square co-planar geometry to four equivalent Au and eight equivalent Ge atoms.
