NaBeAu is Hg_xSn structured and crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one NaBeAu cluster. Na(1) is bonded in a 2-coordinate geometry to one Be(1) and one Au(1) atom. The Na(1)-Be(1) bond length is 1.45 Å. The Na(1)-Au(1) bond length is 1.38 Å. Be(1) is bonded in a distorted single-bond geometry to one Na(1) and one Au(1) atom. The Be(1)-Au(1) bond length is 0.95 Å. Au(1) is bonded in a 2-coordinate geometry to one Na(1) and one Be(1) atom.
