Materials Data on Ba(GeAu)2 by Materials Project
Ba(AuGe)2 crystallizes in the orthorhombic Immm space group. The structure is three-dimensional. Ba is bonded in a 8-coordinate geometry to eight equivalent Au and eight equivalent Ge atoms. There are four shorter (3.53 Å) and four longer (3.59 Å) Ba–Au bond lengths. All Ba–Ge bond lengths are 3.60 Å. Au is bonded in a 4-coordinate geometry to four equivalent Ba and four equivalent Ge atoms. There are two shorter (2.70 Å) and two longer (2.74 Å) Au–Ge bond lengths. Ge is bonded in a 9-coordinate geometry to four equivalent Ba and four equivalent Au atoms.
