Be2RuAg crystallizes in the triclinic P1 space group. There are two inequivalent Be sites. In the first Be site, Be(1) is bonded in a 5-coordinate geometry to one Be(2) and four equivalent Ag(1) atoms. The Be(1)-Be(2) bond length is 2.32 Å. There are a spread of Be(1)-Ag(1) bond distances ranging from 2.42-2.96 Å. In the second Be site, Be(2) is bonded in a 2-coordinate geometry to one Be(1) and two equivalent Ru(1) atoms. There is one shorter (1.94 Å) and one longer (2.11 Å) Be(2)-Ru(1) bond length. Ru(1) is bonded in a 1-coordinate geometry to two equivalent Be(2) and one Ag(1) atom. The Ru(1)-Ag(1) bond length is 1.01 Å. Ag(1) is bonded in a single-bond geometry to four equivalent Be(1) and one Ru(1) atom.
