Materials Data on ZnAu3 by Materials Project
Au3Zn crystallizes in the tetragonal I4_1/acd space group. The structure is three-dimensional. there are three inequivalent Au sites. In the first Au site, Au is bonded in a distorted bent 120 degrees geometry to two equivalent Zn atoms. Both Au–Zn bond lengths are 2.74 Å. In the second Au site, Au is bonded in a 12-coordinate geometry to four equivalent Zn atoms. There are two shorter (2.79 Å) and two longer (2.80 Å) Au–Zn bond lengths. In the third Au site, Au is bonded in a distorted square co-planar geometry to four equivalent Zn atoms. All Au–Zn bond lengths are 2.87 Å. Zn is bonded in a distorted q6 geometry to ten Au atoms.
