Materials Data on BaSiAu by Materials Project
BaAuSi crystallizes in the hexagonal P-6m2 space group. The structure is three-dimensional. Ba2+ is bonded in a 6-coordinate geometry to six equivalent Si4- atoms. All Ba–Si bond lengths are 3.57 Å. Au2+ is bonded in a trigonal planar geometry to three equivalent Si4- atoms. All Au–Si bond lengths are 2.53 Å. Si4- is bonded in a distorted trigonal planar geometry to six equivalent Ba2+ and three equivalent Au2+ atoms.
