BeAuSe is Indium-like structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two BeAuSe clusters. Be(1) is bonded in a single-bond geometry to one Au(1) atom. The Be(1)-Au(1) bond length is 0.09 Å. Au(1) is bonded in a distorted single-bond geometry to one Be(1) and one Se(1) atom. The Au(1)-Se(1) bond length is 0.44 Å. Se(1) is bonded in a single-bond geometry to one Au(1) atom.
