Na Au Se
NaAuSe is Hg_xSn structured and crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one NaAuSe cluster. Na(1) is bonded in a distorted bent 120 degrees geometry to one Au(1) and one Se(1) atom. The Na(1)-Au(1) bond length is 1.92 Å. The Na(1)-Se(1) bond length is 1.23 Å. Au(1) is bonded in a distorted single-bond geometry to one Na(1) atom. Se(1) is bonded in a single-bond geometry to one Na(1) atom.
