BeYRu is Hg_xSn structured and crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one BeYRu cluster. Be(1) is bonded in a single-bond geometry to one Y(1) atom. The Be(1)-Y(1) bond length is 0.77 Å. Y(1) is bonded in a water-like geometry to one Be(1) and one Ru(1) atom. The Y(1)-Ru(1) bond length is 0.78 Å. Ru(1) is bonded in a single-bond geometry to one Y(1) atom.
