Ta Be Be Au
Be2TaAu crystallizes in the monoclinic Pm space group. The structure is zero-dimensional and consists of one Be2TaAu cluster. There are two inequivalent Be sites. In the first Be site, Be(1) is bonded in a single-bond geometry to one Ta(1) and one Au(1) atom. The Be(1)-Ta(1) bond length is 1.42 Å. The Be(1)-Au(1) bond length is 0.20 Å. In the second Be site, Be(2) is bonded in a single-bond geometry to one Au(1) atom. The Be(2)-Au(1) bond length is 0.38 Å. Ta(1) is bonded in a single-bond geometry to one Be(1) atom. Au(1) is bonded in a bent 150 degrees geometry to one Be(1) and one Be(2) atom.
